Thalamus

Inside out Developmental Psychology Paper The brain is the most complex part of the human body. The brain can be divided into three basic units, the forebrain, midbrain and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem and the ball of tissue is called the cerebellum. The hindbrain controls the body’s vital functions such as heart rate and respiration. The cerebellum coordinates movement and is involved in learned routine movements. The upmost part of the…

“It's dark out, and you're home alone. The house is quiet other than the sound of the show you're watching on TV. You see it and hear it at the same time: The front door is suddenly thrown against the door frame.’ ‘Your breathing speeds up. Your heart races. Your muscles tighten.”- (Layton) Fear is a chemical reaction that tells our brain and bodies that something is wrong. It is a survival instinct that that keeps us safe and out of danger. But what chemical reactions happen when you are afraid…

anatomical model is called the Papez circuit.[2] In the year of 1948 scientist Yakovlev proposed Yakovlev's circuit in the command of emotions involving the anterior, insular, , temporal , orbitofrontal and lobe cortex, the dorsomedial nucleus of thalamus and amygdala.[3] In 1952, Paul D. MacLean used the name “limbic system” to describe Broca's limbic lobe and related subcortical nuclei as the combined neural substrate for emotion.[1] He was also pivotal in the proposal and definition of the…

environmental stimuli and their states, while the dorsal system assimilate with the emotional influence and their performance of executive functions. (Ceylan & Saym, 2012) The resulting emotional response from the limbic region transmits to the thalamus by which it defines the incoming information through the sense organs. According to Ceylan and Saym, the long-term potentiation (LTP) delivers a consolidating neural mechanism, in which a certain external event becomes the basis for long-term…

forebrain is the highest part of you brain. Essentially, it separates humans from all the other animals. This consists of 5 parts which are the limbic system, the thalamus, the hypothalamus, the basal ganglia, and the cerebral cortex. The limbic system processes emotions, how we recognize emotions, and how we express them. The thalamus sorts information coming from all these different parts. The Hypothalamus monitors pleasurable activities and releases hormones in response to emotions. The…

Csernansky, 2010) In particular, these studies have shown that synchronization in the beta frequency band in thalamocortical region was correlated with working memory. In addition, it was found that a reduction of the activity of mediodorsal thalamus and thalamus cortical areas leads to a deficiency in the processes of acquisition and maintenance of information. (Uhlhaas, Roux, & Singer, 2013). Besides the beta frequency synchronization, synchronization of these studies showed correlation in…

The heart is considered as the center of wisdom, passion, and emotions by many a people. This emanates from the fact that people report experiencing emotional states and the feeling love in the area of the heart. However, these feelings have been conventionally attributed to the brain. Recent studies have disputed this fact with physiological mechanisms being explored to ascertain how the heart communicates with the brain and as such influence the health, emotions, perceptions, and processing of…

Overview Background Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years. Clinically, it manifests with a paroxysmal, transient loss of memory function. Immediate recall ability is preserved, as is remote memory; however, patients experience striking loss of memory for recent events and an impaired ability to retain new information. In some cases, the degree of retrograde memory loss is mild. Many patients are anxious or agitated and may repeatedly ask…

Researching the correlation amongst brain anatomy and physiology is a primary pursuit of neuroscience. Simplistic in its composition the brain is astoundingly the most complicated machine known to man. This mass of protein and fat in addition to being responsible for maintaining homeostasis also encompasses attributes that not only make us unique, creative, empathetic, moreover human. Overview of structure & function The brain of humans is primarily composed of two general classes of…

responsible for proper function of the nervous system. Functional magnetic resonance imaging is used to study anatomical structure and measure tissue volume of the left and right hippocampus, caudate nucleus, and thalamus. The caudate nuclease aids in learning and memory and the thalamus, which is part of the limbic system, aids in sensory perception and regulation of motor functions. Secondly, blood was collected from each participant before beginning the program and immediately after…
