It it between the somatosensory cortex and the cuneus. The Precuneus is responsible for episodic memory, one's reflections upon self and realisations of consciousness. An interesting aspect of this area of the brain is that it is responsible for visualising imaginations, scenarios that have actually never occurred. For this process, information from actual episodic memory is put together. In addition, it is also responsible for how one views themselves according to what they are imposed to be compared to. Certain labels that we put on ourselves are also caused by this area.

There a two substantia nigrae on each side of the midline of the midbrain. Substantia nigra is composed of two main regions: substantia nigra pars compacta and substantia nigra pars reticulata. The substantia nigra’s dark black colour comes from the substantia nigra pasr compacta region, where a large number of dopmaine-producing nuerons have accumulated. The dopamine-producing neurons express a dark pigment named neuromelanin. The dopamine neurons are projected to the striatum of the brain. These dopmaine neurons form fibers, which is named as the nigrostriatal pathway. This pathway plays a significant role in the facilitation of movement.Therefore, movement is the major concern of substantia nigra, which can also be deduced by observing patients with Parkinson’s disease, which is a neurodegenerative disorder that destroys the dopamine-producing neurons in the substantia nigra.

Emotions, habitual behaviours and voluntary movements are controlled by a group of structures: Basal Ganglia. They are found deep within the  cerebral hemispheres.

Even though every structure of Basal Ganglia has its own role, the overall system can be considered as a network. This network simply functions in motor control to inhibit competing movements as well as to facilitate movements. Intentional movements such as grabbing an object are associated with the motor plans controlled by Basal Ganglia.

The basal ganglia are a group of subcortical nuclei in the brain, and localized under the forebrain and top of the midbrain. They are positioned deep within the cerebral hemispheres. 

Basal ganglia are strongly interconnected with several brain areas such as the cerebral cortex, thalamus, and brainstem. The basal ganglia are responsible for voluntary motor movements control, procedural learning, habit learning, eye movements, cognition, and emotion. 

Basal ganglia supports smooth and fluid movement. Basal ganglia damage may cause rigidity and slow movement or Parkinson’s disease.

The main components of the basal ganglia are the striatum; both dorsal striatum and ventral striatum, globus pallidus, ventral pallidum, substantia nigra, and subthalamic nucleus. These structures have a complex internal anatomical and neurochemical organization.

Nucleus Accumbens is found in the basal forebrain. There is one in each hemisphere, and it is between the caudate and putamen. The nucleus accumbens is considered part of the basal ganglia and also is the main component of the ventral striatum. 

It controls reward, motivation, and addiction. Dopamine is released into the neurons in nucleus accumbens when a rewarding behavior occurs. This results in a repetition of that behavior. 

Dopamine is useful in storing memories because it can link certain environmental stimuli to pleasure. Later on, these memories help us recognize stimuli that could give us pleasurable experiences. In addictive processes, it may be that the memories of the initial pleasurable drug experience and the stimuli associated with it becomes too strong.  However, in cases like using heroin, this expectation is not met and the person injects excessive amounts of the drug to achieve the pleasure level in his/her memory which can eventually lead to death.]]> 2019-04-24 21:11:45 UTC https://padlet.com/stmorris6/uinqkz79bqt/wish/353922497 Alara Kaplanoglu - Cingulate Cortex https://padlet.com/stmorris6/uinqkz79bqt/wish/354005900 Cingulate cortex is a section of cerebral cortex found in the medial portion of the hemispheres.

It is primarily responsible for the selection of voluntary movements in response to internal or external stimuli. Some of these movements include reaching or grasping with hands, or even maintaining posture when standing. The premotor cortex plays a very essential role in our daily lives, as it is required in every basic task that involves a person to move a part of their body. The signals sent from the premotor cortex combine with the signals from the primary motor cortex in the brain stem, in order to create unified and intentional motions. A secondary function of the premotor cortex is that it is involved in the processes of decision-making, similar to the prefrontal cortex.

Extra Info on Structure: The premotor cortex is generally considered to be composed of four distinct parts: the upper, lower, dorsal and ventral premotor cortex.  These are further divided into the region towards the front of the brain and the region towards the back, named the rostral premotor cortex and caudal premotor cortex.

The pineal gland is key to the body's internal clock because it regulates the body's circadian rhythms. Circadian rhythms are the daily rhythms of the body, including signals that make someone feel tired, sleep, wake up, and feel alert around the same time each day. The pineal gland secretes melatonin, which is a hormone that helps regulate circadian rhythms. Melatonin is produced according to the amount of light a person is exposed to however, the pineal gland releases greater amounts of melatonin when it is dark, which points to melatonin's role in sleep. 
Many supplement manufacturers offer melatonin as a "natural" sleep aid.

 The pineal gland was one of the last brain organs to be discovered and has been the subject of much mythology and speculation. The seventeenth-century French philosopher Descartes thought the soul was located in the pineal gland.

For example, FMRI brain imaging techniques revealed that precuneus is activated when patients are asked to remember certain images that they have seen before with verbal questions.

 Precuneus is also related with imagination and mental images. When a setting, object or even a human face is described to an individual through words (auditory stimuli), the process of creation of a mental image takes place in the precuneus. 

The process of motor imagery also takes place in the precuneus. This way, when an individual performs a motoric activity such as dancing, riding a bike or swimming, the individual feels and imagines themselves doing that activity, and a mental image of themselves doing the activity
 is created. ]]> 2019-04-26 12:24:10 UTC https://padlet.com/stmorris6/uinqkz79bqt/wish/354419659 TARA ILLEL taraillel2002 https://padlet.com/stmorris6/uinqkz79bqt/wish/354423718 The visual cortex

The visual cortex is the part of the brain which is responsible of processing visual information. The visual cortex is divided in to five different parts according to structure and function.It is known that in the brain the visual cortex is located inside the occipital lobe. Also visual nerves which play a crucial role in our sight run directly from our eyes to primary visual cortex located in the occipital lobe. The primary visual cortex which is the part of the visual cortex that first receives the sensory inputs which is the, objects and generally all things wee see.This area of the visual cortex is also known as striate cortex.Both of the hemispheres of the human brain contains visual cortex. As it can be interpreted the the visual cortex in the left hemisphere receives signals from the right visual field and the visual cortex in the right hemisphere receives signals from the left visual field.. Shortly the visual cortex is the most crucial and primary region of the human brain that receives, integrates and processes the things that it observes which can also be inferred as visual information that is relayed from our retina.

The basal ganglia are structures found deep within the cerebral hemisphere. 
 
The composition of the basal ganglia includes: Puttamen , Caudate nucleus, Globus pallidus , the Subthalamic nucleus and the Substantia nigra.
 
The Basal Ganglia’s functions include control of voluntary motor movements such as when someone tries to make an intentional movement the basal ganglia helps to aid the movement by allowing motor plans linked to that movement to become activated. In addition, the Basal Ganglia controls emotions, habitual behaviors and eye movements. 
 
 Basal ganglia support the fluid movement. Damage to the Basal ganglia may cause rigidity along with Parkinson’s disease and ticks such as uncontrolled repeated movements.

 It is responsible for relaying information from the sensory receptors to proper areas of the brain where it can be processed.

It diagnoses different sensory information that is being transmitted to the brain including auditory, visual, tactile (relating to touch),  and gustatory (relating to taste) signals. After that, it directs the sensory information to the different parts and lobes of the cortex. If this part of the brain is damaged, all sensory information would not be processed and sensory confusion would result.

Thalamus is a part of the limbic system.]]> 2019-04-26 16:12:30 UTC https://padlet.com/stmorris6/uinqkz79bqt/wish/354511332 Ahmet Eren - https://padlet.com/stmorris6/uinqkz79bqt/wish/354517657 Medulla Oblongata is located between the brain and spinal cord. It is the lowest position of hindbrain.
 It carries communications between these two areas. It is responsible for control of autonomic functions, regulation of mood, motor movements and relaying the nerve signals between the brain and spinal cord. ]]> 2019-04-26 16:27:46 UTC https://padlet.com/stmorris6/uinqkz79bqt/wish/354517657 Mayra Kalaora https://padlet.com/stmorris6/uinqkz79bqt/wish/354659043 The Subiculum
The subiculum is located in the primary output region outside the hippocampus, and is part of the temporal lobe of the brain. As it is in the output region of the hippocampus, its functions include learning and memory. It is also important for spatial navigation, mnemonic (symbol) processing, and regulating the stress of the body by inhibiting the HPA axis - our central stress response system. Although the subiculum has been associated with the onset of epilepsy, neuroscientists observe an inconsistency when connecting it to cognitive disorders. Damage to the subiculum may result in memory impairment, disorientation, and stress. ]]> 2019-04-27 10:21:59 UTC https://padlet.com/stmorris6/uinqkz79bqt/wish/354659043 Iris YASAR https://padlet.com/stmorris6/uinqkz79bqt/wish/354694420 ENTORHINAL CORTEX
The entorhinal cortex is located in the medial temporal lobe of the brain. It is part of a widespread network responsible for memory and navigation. It is the main interference between the hippocampus and the neocortex. This system plays and important role in memory formation, memory consolidation, and memory optimisation in sleep. It is also responsible for pre-processing the input.

As highlighted in the MRI scan below, the orbitofrontal cortex is located in the front part of our brain, which is the frontal lobe. It is specifically a part of the prefrontal cortex and belongs to the limbic system. The limbic system is responsible for the emotional and behavioural responses. The function of the orbitofrontal cortex is that it  helps us weigh the consequences of events, especially socially. It is highly involved in the process of decision-making. It also compares the different outcomes of an event, helping us to choose the realtively best option when making decisions. Additionally, it is connected with the amygdala and it is hypothesized that the orbitofrontal cortex is also responsible for the physical responses to emotions, such as the nervous feeling in the stomach.

It is a part of the limbic system. It is located around the corpus callosum. The area highlighted with green in the picture below is 'cingulate gyrus'.

Cingulate Gyrus is associated with pain processing, emotion, memory, self-regulation and behavior regulation. It regulates emotions and pain. It drives the body's conscious responses to unpleasant experiences. It is involved in predicting and avoiding negative consequences. It is important for the memory to learn to avoid negative consequences. . In addition it also helps to regulate autonomic motor functions. These are bodily functions conducted unconsciously such as heart rate, digestion, urination etc.

It is located right in the centre of the brain, in between two lobes, on the hypothalamus. 

Thalamus serves as a relay station for almost all information that comes and goes to the cortex. It plays a role in pain sensation, attention, alertness and memory. In detail, it is responsible with consciousness, sleepiness, alertness, and transmitting sensory information to cerebral cortex.
