next topic I will cover is the description of memory formation in the hippocampus. The hippocampal formation is in the temporal lobe. It is small part of the limbic cortex. The formation is a forebrain structure. It is comprised of the hippocampus proper‚ denate gyrus and the subiculum. From our reading‚ I learned that the entorhinal cortex is responsible for the primary input to the hippocampal formation. This formation is very precise. We learned in our reading that regardless of how or where you look

children with age lower than‚ on average‚ twelve-years-old have less change to speak with foreign accent when they learn a second language. The scientists uses the critical period theory to explain those capacity and also introduce the concept of cerebral lateralization‚ process in the brain that made the hemispheres specialize in particular functions. The critical period theory is supported by studies with patients suffering from aphasia‚ loss of language abilities result of brain damage. Thus‚

Roger W. Sperry Introduction Born August 20‚ 1913‚ Roger W. Sperry‚ won the 1981 Nobel Prize in physiology and medicine. He shared it with two other scientists‚ Wiesel and Hubel‚ for research on the nervous system and brain. They were praised for demonstrating the difference between the two hemispheres of the brain and special functions of the right brain. (Roger W. Sperry Biography (n.d.) A moderately controversial psycho biologist‚ Sperry changed the history of psychology. In 1935‚ Sperry

Describe and evaluate biological explanations of OCD (10 marks) The biological approach as an explanation of OCD believes that the disorder is caused by a fault in our body‚ either through genes‚ hormones‚ the brain‚ or neurotransmitters‚ therefore suggesting that OCD is caused by our nature‚ rather than our upbringing. This means that since we are born with the body we have‚ if we have OCD‚ it is innate within us. One biological explanation for OCD is the genetic explanation. The genetic

across the left side of the patients face‚ the patient felt that same movement sensation on the missing right hand. Dr. Ramachandran theorizes that the left side of the body is mapped to the right side of the brain through a strip of cortex called the somatosensory cortex. When there is a missing limb‚ the part of the brain the corresponds to that limb no longer gets any input. The Dr. has learned that sensory signals that‚ normally‚ only activate facial senses‚ are now invading the vacated territory

The brain is one of the most important vital organs that make up the human body. It is the body’s control center and plays a role in every function that humans perform by sending and receiving signals to and from all of the parts of the human body. The brain has three different components that make up its structure and those components are the cerebrum‚ cerebellum‚ and brain stem. Each of theses components can each be broken down into their own individual parts and each of those parts plays a role
Premium Brain Nervous system Neuron
The limbic system is a neural system located below the cerebral hemispheres of the brain. Three structures that are part of the limbic system are the hypothalamus‚ hippocampus‚ and the amygdala. These three structures work together as a whole making it feasible for the body to function properly. The hypothalamus is a small‚ but busiest part of the brain located just below the thalamus and is mainly concerned with homeostasis. It is an important link in the command chain governing bodily maintenance

The basal lamina of the cerebral microvasculature is in close connection to astrocytes and neurons that regulate the surrounding microcirculation‚ hence it is termed intrinsic innervation. Intrinsic afferents originate from subcortical neurons‚ such as the basal forebrain‚ the raphe
