the brains ability to repair itself/regenerate. Demonstrated by the teen who suffered a stroke that damaged the language section of the brain. Overtime and practice she was able to build it back up and regain function.

The localization of function is the theory that certain brain parts have certain functions. One study related to this would be Maguire study.

rileykale07 — 2024-09-09 15:24:18 UTC

The idea of localization of function is that you can pinpoint a behavior to a certain part of the brain. A study to demonstrate this is the Gage study when a man named Gage was impaired in the brain with a stake.

Dopamine is a neurotransmitter that excites feelings of love and pleasure. It was researched in the study Fischer et al.

Adriana Zelaya - Localization of Function

2024-09-09 15:28:20 UTC

Localization of function is pinpointing which part of the brain is responsible for which function. A study that uses the localization of function idea is the EP study, where he destroyed his amygdala and hippocampus, and lost his episodic and semantic memories.

Um the MRI study where they like tested people for memory and stuff. It was like the college students in a room

ok got more... they show images, angry, sad, happy faces on screens and then they use fmri scanning to test which parts of the brain are being used to recall

Robert Sapolsky’s study on affect of cortisol on baboons. He observed that baboons with higher levels of cortisol had different social behaviors compared to those with lower levels. Baboons with high cortisol levels tended to be more aggressive, anxious, and had weaker social bonds.

Localization of function is when a specific function/behavior can be attributed to a location in the brain. Like when Phineas Gage had his frontal lobe removed after a railing accident & he began to have a drastic change in his moral reasoning & decision making.

2024-09-09 15:29:53 UTC

The EP study showed that the formation and production of semantic and episodic memories is not possible without the function of the amygdala and hippocampus. EP suffered from viral encephalitis which destroyed the function of his amygdala and hippocampus. He could no longer form semantic or episodic memories, however he could form procedural memories without knowing he could do so.

rileykale07 — 2024-09-09 15:30:22 UTC

Neuroplasticity is the idea that your brian can regain memory of a how to partake in a task or remember an idea. This was demonstrated in a case study when an alzheimer's patient still had the ability to remember to get to the kitchen but forgot all other things like names

Avery Walters

One technique to study the brain is an MRI. A MRI shows researchers images of people's brain and the structure. One study that uses an MRI is the London Cab Driver Study. This was used to examine the size of the hippocampus in the cab driver's brains compared to normal people to see if the drivers had better memories compared to non-taxi drivers. The findings showed that the cab driver's did in fact have a bigger hippocampus.

Neuroplasticity is the idea that if the brain is damaged, it has its own ability to "repair" or reconnect itself. The Jody brain study is an example for Neuroplasticity.

rileykale07 — 2024-09-09 15:32:16 UTC

Neurotransmission is the process of a neuron shooting within your brain. It passes things like hormones through your neurons helping you to maintain homeostasis. A study to demonstrate this is when rats were tested with different drugs.

Neuroplasticity

2024-09-09 15:33:18 UTC

Neuroplasticity is the brains ability to rebuild destroyed neuron connections. One study that shows this is Jody, who was a little girl who had half of her brain removed, but was able to fully heal, and regain what she had lost. Younger children have more plastic in their brains, which allows them to recover quicker than adults.

2024-09-09 15:34:59 UTC

A technique used in psychology to study the brain is an MRI. An MRI uses waves to make a detailed image. This is used in psychology to study PTSD to see differences in the brain.

Neuroplasticity is the brains ability to reorganize itself by forming new neural connections throughout life. One study that goes over neuroplasticity is the study done by Eleanor Maguire and colleagues (2000) who studied the brains of London taxi drivers. In London, taxi drivers went through extensive training called "The Knowledge," where they memorized the layout of London’s streets. Maguire used MRI scans to compare the brains of these drivers to non-taxi drivers. The study found that the posterior part of the hippocampus was way larger in the taxi drivers than in the control group. The size of this brain region was directly correlated with how long the individual had been a taxi driver

Cameron Stevenson

Neuroplasticity is the brain's function to reorganize itself after injury or trauma. One study example of Jody, who had a hemispherectomy & still was able to learn functions that should've been localized in the missing part of her brain.

The role of oxytocin is to influence trust in others and decrease awareness of danger/risk. A study that proves this is Baumgartner. In this study participants took questionnaires before and after administration of oxyctocin. The results found that the oxyctocin group was more likely to trust others than the control. Thus proving that oxytocin decreases awareness of risk and increases trust.

2024-09-09 15:36:27 UTC

adrenaline is a hormone that creates your "fight or flight" response, this was studied during the experiment where the men crossed bridges with hot girls at the end!

Adrian Vo- Role of one technique (E.P. Case study)

EP had encephalitis and it destroyed his amygdala and hippocampus. When he was interviewed and observed with a MRI scan. Er could not use his episodic or semantic memory, but he could use his procedural memory. Through practice he learned new skills with muscle memory, but he had no knowledge that he knew how to do the task. This proved the connection of the hippocampus and Amygdala affecting memory and without both memory could not be produced.

Hormones

2024-09-09 15:36:35 UTC

Oxytocin is a hormone that is associated with love and trust. A study that can be used to prove this is the Baumgartner study, where they found that oxytocin lowers one's ability to judge risky or dangerous situations.

rileykale07 — 2024-09-09 15:37:44 UTC

A technique to study the brain is through EEG tests. This was seen in a study where patients were shown images of "blobs" and shapes and they had to respond to what they thought it was. EEGs track brain activity. They highlight which parts of the brian are working at certian times.

2024-09-09 15:37:54 UTC

The lost in a mall study where participants were told 3 real stories and one fake on about how the time that they got lost in a mall in order to see if the memories of the participants could be changed to make them remember something that didn't happen by adding a couple of real details such as the clothes they wore, a toy they had, or even something they bought. This study was to test whether or not the participants memories could be changed to remember an event that didn't happen through an idea called reconstructive memory. (i think)

One technique used to study the brain is an fMRI which was used in the Fisher et al study. He used an fMRI to examine the role of dopamine in early romantic love. The study aimed to test their hypothesis that dopamine areas of the brain are linked with being in love. The study's results showed that viewing photos of a loved one activated the VTA and other areas of the brain compared to looking at photos of an acquaintance.

neurotransmition is where messages are sent through out the body in the CNS. Kasamatsu and Hirai, 1999 wanted to see how sensory deprivation afects the brain and how seratonin affects behavior. the men were exposed ot col weatehr no food and drink and couldnt talk, conclusion was that seratonin had increased therfore menaing that sensory deprivation allowed for seratonin to be released casuing hallucinations.

Neuroplasticity is the response to a change that causes structures and functions in the nervous system to change. An example of this is if someone were to have a stroke. A case that proves this is the Maguire case. This case involved taxi drivers and short term memory.

2024-09-09 15:41:04 UTC

Neuroplasticity is the brains ability to reorganize and adapt to new information following learning. The brain is also able to adapt to and combat damage done to the brain. One study that demonstrates neuroplasticity is Chloa and Blizinsky. In this study, 50,000 participants with the 5-HTTLPR gene data was collected from 29 countries to test the effects of collective cultures on social genetic adaptations. THe study found that in collective communities, a shorter 5-HTTLPR gene was common and correlated with a lesser population with mental disorders. This proves neuroplasticity as the change to the genetics was caused by being a member of a collective community.

Neurotransmission

2024-09-09 15:41:16 UTC

Neurotransmission is the process of a neuron firing in the brain. They pass along hormones through neurons. This can be seen in the Rogers and Kesner study, where rats were given acetylcholine to see its role in the formation of memory.

Jalayah Thompson

2024-09-09 15:42:07 UTC

The role of the hormone oxytocin, is to lower your ability to judge dangerous situations and ability to objectively discern. Baumgartner (2008) is study in correlation.

2024-09-09 15:42:18 UTC

neuroplasticity is being able to form new neural connections seen in the maguire study where taxi drivers hippocampus' were larger than others due to memorization of the area required in their job, this also can be used for localization of funcation

hormones

rileykale07 — 2024-09-09 15:42:47 UTC

Hormones are part of the process within the parasympathetic nervous system. They are released within your brain's neurons making you feel certain ways. One study of the "love hormone" or oxytocin was conducted when a man had oxytocin amounts and it was measured the amount of women he attracted to him.

Role of Technique in Studying the Brain

2024-09-09 15:44:10 UTC

One technique that can be used to study the brain is an fMRI. fMRIs show you what function goes along with what part of the brain, and allows us to see brain activity. One study that shows this is the McGuire study, where they proved that the hippocampus is attcached to our memories.

McGuagh and Cahill- Localization of function

2024-09-09 15:44:45 UTC

In the study 2 different groups were presented with different versions of the same story. One was more emotionally stimulating while the other was considered boring. Researcher believe that emotion memories are more easily remembered than non-emotional memories. The release of adrenaline stimulates the amygdala and effects emotional memories. They found out that the significant role of the amygdala on memories is with emotional arousal. This is because during the test the participants were asked to recall the story weeks later and they made it more traumatic, but more clearer.

locilization of function

2024-09-09 15:44:45 UTC

Phineas Gage, this studies shows localization becuase he was struck with a metal pole into the left frontal lobe. this caused behavior chanegs as he before was a kind man and after was rude and disrespectful. thus shwoing that parts fo our brian have certain jobs.

2024-09-09 15:45:14 UTC

neurotransmission sends messages to the brain so our bodies can respond to the stimuli, one neurotramsmitter is noreprinephrine which is an excitatory transmitter used for alertness and arousal

2024-09-09 15:45:58 UTC

One neurotransmitter is acetylcholine. The role of this NT is to consolidate memories in the Hippocampus. One study that proves this is Rogers and Kesner. The aim of the study was to determine the role of acetylcholine in memory formation. The procedure was to inject rats with scolopamine and test if they could recall how to navigate through mazes. The study found that the scolopamine group took longer to navigate and made more mistakes while the other group remembered more clearly and navigated quicker. Proving acetylcholine has an active role in memory consolidation.

Neurotransmission is the transfer of information between neurons. In other words, the process of chemical messages throughout the brain. The neurotransmitter serotonin can affect moos, sleep, and arousal. In the study Cases et al (1995) the affect, or role, that serotonin has on aggression levels.

Jalayah Thompson

2024-09-09 15:50:27 UTC

One technique that is used to study the brain is an fMRI. This is used as an imaging scan that tells the activities of the brain in certain places. One study that has used an fMRI is Cases et al (1995).

Landon S. Localization

2024-09-09 15:51:22 UTC

Localization of function refers to the idea that specific areas of the brain are responsible for particular cognitive or behavioral functions. One classic example involves the Broca's area, a region in the left frontal lobe responsible for speech production. A famous study supporting this idea is Paul Broca's work in the 1860s. Broca studied patients who had difficulty producing speech but could still understand language. One of his most well-known patients named Tan could only say the word tan but he understood spoken language. After Tan died, Broca performed an autopsy and discovered a lesion in the left frontal region of the brain, now called Broca's area. This led Broca to propose that this specific brain region is crucial for speech production, providing strong evidence for the localization of function. This finding was later supported by other research showing that damage to Broca's area typically results in expressive aphasia, where a person can understand speech but struggles to produce coherent language, highlighting the specific role this area plays in language processing.

2024-09-09 15:52:04 UTC

One role of technology in studying the brain is to help accurately show the structure or parts of the brain. One study where this is demonstrated is the EP study. MRI scans were used to view the structures of EP's hippocampus and amygdala. This was useful as it was able to show the destruction to these areas of his brain, and therefore show why the episodic and semantic memories were unable to be made.

Neuroplasticity Resenzweig study

2024-09-09 15:56:24 UTC

In the study of Resenzweig, the study wanted to test the individual's environment and the affect of their brain development by using rats. As an effect of the experiment the cerebral cortex in the brains of the rats in the enriched condition was heavier than the other conditions.
