PS1005 Provide an overview of the principal structures of the midbrain‚ hindbrain and forebrain and their functions. The human nervous system consists of many structures. We distinguish between the central- and the peripheral nervous system. The two major subdivisions of the central nervous system are the brain and the spinal cord‚ which is found in the spinal column. The peripheral nervous system consists of the nerves outside the brain and the spinal cord. The spinal cord communicates

The cerebral cortex outer layer of the cerebrum has the two largest hemispheres that cover the upper part of the brain which are divided into smaller portion called lobes. Corticalization is an increase in size of the wrinkling of the cortex and without this we would not be smarter than any other animal. Cerebral hemispheres are divided into right and left sides of the cortex connected by thick band axon fibers called corpus. Hemispheric specialization‚ testing only one side of the brain by a process

breathing. Reticular Formation A nerve network in the brainstem that plays an important role in controlling arousal. Thalamus The brains sensory switchboard‚ located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla. Cerebellum The "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance. Limbic System Doughnut-shaped neural system
Premium Brain Neuron Cerebral cortex
The corpus callosum(CC) links the cerebral cortex of the left and right cerebral hemispheresand is the largest fibre pathway in thebrain. It is approximately 10cms in length and is shaped‚ like most of the supratentorial structures‚ in a gentle upwardly convex arch. The postrior portion of the corpus callosum is called thesplenium; theanteriois called thegenu(or "knee"); between the two is the "body"‚ of the corpus callosum. genu : forceps minor : connect medial and lateral surfaces of the

Alec Connell Psy-101-22 W Professor Kulpa6/16/2014 The Brain Neuroscientists have proven that the activity in the brain is altered when an individual is subject to extremely stressful or exciting circumstances. In the documentary multiple unique qualities of the brain are explored‚ studied‚ and tested to determine how we can benefit from understanding the functions of the brain. Learning about the fundamentals of the brain in the text made understanding the procedures our brain undergoes to

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch

Cerebral Cortex and Frontal Lobe The outer layer of our forebrain consists of the cerebral cortex. The cerebral cortex is so significant since it controls our ability to learn and store complex and abstract information. Also‚ it is our control and information processing center. The cerebral cortex consists of many interconnected neurons that are quite useful. The cerebral cortex covers the frontal lobe. This lobe is so important because it controls our organization‚ planning‚ and creative thinking

It is important to note Lashley does not oppose the idea that there are specialized functional areas of the brain‚ mainly the sensory functions that are localized. The visual cortex it probably the best example of a specialized area of the brain; Damage to the visual cortex produces a direct proportion to the damage of visual ability in an animal. Lashley performed experiments with
