The cerebral cortex is divided into four sections‚ alluded to as flaps: the frontal projection‚ parietal projection‚ occipital flap‚ and fleeting

Comparison of Brain Structure in Mammals‚ Amphibians‚ and Birds The brain is a complex structure in all living species‚ even though they differ greatly in mammals‚ amphibians‚ and birds. It is the most important part of the body‚ because it maintains homeostasis and assists in every function. The brain structures of the three vertebrates‚ mammals‚ amphibians‚ and birds‚ have similar features and functions. There is still a great difference in the size‚ and importance of these structures in

A. Effects on catecholamine release and reduction of cerebral metabolic rate Cerebral hypoxic injury is known to be associated with a massive catecholamine increase in central and peripheral norepinephrine concentrations are commonly seen with cerebral hypoxic injury. Catecholamines may impoverish outcome from cerebral ischemia‚ possibly by stimulating central _2-receptors (Figure 2.20). Neuronal damages are results of icreased norepinephrine due to the elevation of metabolic demand and alteration

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

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

are the precentral gyrus and the frontal cortex which is right beside it which have motor capabilities. Frontal lobes are also one of the four main regions of the cerebral cortex. This is where all your planning and decision making goes on and how you solve problems (About.com‚ 2012). 6. Cerebrum Cerebrum means cerebral hemispheres. When comparing the cerebrum to the brain stem it is known to be more complex and have an adaptive process such as your learning capabilities‚ your perception

A cerebral hemorrhage (also spelled haemorrhage) is a subtype of intracranial hemorrhage that occurs within the brain tissue itself. It is alternatively called intracerebral hemorrhage (ICH). It can be caused by brain trauma‚ or it can occur spontaneously in hemorrhagic stroke. Non-traumatic intracerebral hemorrhage is a spontaneous bleeding into the brain tissue.[1] A cerebral hemorrhage is an intra-axial hemorrhage; that is‚ it occurs within the brain tissue rather than outside of it. The other

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
