It was found that from the age of 7, these are larger in males thn in females. https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119269930 2016-08-22 23:42:22 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119269930 The mygdala is involved in the autonomic responses associated with fear and hormonal secretion https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270303 2016-08-22 23:45:49 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270303 primary function https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270408 Amygdala is the integrative center for emotions, emotional behavior, and motivation. If the brain is turned upside down the end of the structure continuous with the hippocampus is called the uncus. If you peel away uncus you will expose the amygdala which abuts the anterior of the hippocampus. Just like with the hippocampus, major pathways communicate bidirectionally and contain both efferent and afferent fibers.]]> 2016-08-22 23:46:37 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270408 https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270639 2016-08-22 23:48:54 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270639 Shown in research to perform a primary role in the processing of memory, decision-making, and emotional reactions, the amygdalae are considered part of the limbic system. https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270650 2016-08-22 23:48:58 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119270650 Hemispheric specializations. https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119271135 There are functional differences between the right and left amygdala. In one study, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala was able to induce either pleasant (happiness) or unpleasant (fear, anxiety, sadness) emotions.

The hormones from the hypothalamus govern physiologic functions such as temperature regulation, thirst, hunger, sleep, mood, sex drive, and the release of other hormones within the body. This area of the brain houses the pituitary gland and other glands in the body.Although this portion of the brain is small in size, it is involved in many necessary processes of the body including behavioral, autonomic (involuntary or unconscious), and endocrine functions, such as metabolism and growth and development.The hypothalamus' primary function is homeostasis, which is to maintain the body's status quo system-wide. Hypothalamic hormones include thyrotropin-releasing, gonadotropin-releasing, growth hormone-releasing, corticotrophin-releasing, somatostatin, and dopamine hormones. These hormones release into the blood via the capillaries (small vessels) and travel to the pituitary gland. Oxytocin and vasopressin are also hypothalamic hormones.The hypothalamus uses a set-point to regulate the body's systems, including electrolyte and fluid balance, body temperature, blood pressure, and body weight. It receives inputs from the body, then makes the proper changes if anything differentiates from this set-point. The set-point can temporarily change, but remains remarkably fixed from day-to-day. https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119272482 2016-08-23 00:11:12 UTC https://padlet.com/lzuidema/7kox7jh9m1yc/wish/119272482
