Running Head: Spatial Navigation in Rats Effects of Lesioned Red Nuclei on Spatial Navigation in Rats Abstract Through cerebellar research we have found that the cerebellum is involved in non-motor functions just as much as it is involved in motor functions. This study looked at the pathway from the cerebellum to the red nucleus to […]

What determines the perceived brightness of objects? Luminance is a physical and objective measure of the intensity of light. The sensation elicited by different luminances is called brightness. However brightness is a subjective measure as it is the perceived amount of light emanating from an object. It may seem logical to expect that luminance and […]

Considered to be an autoimmune disorder, MS attacks the myelin sheaths which surround and protect the nerve fibers. The affected myelin then forms scar tissue (hence the name), also referred to as plaques or lesions, which can damage the nerve fibers and disrupts the transmission of nerve impulses from the CONS (brain and spinal cord) […]

The word ‘seizure’ has been used interchangeably with the terms ‘spasms’ and ‘epilepsy’ because these terms describe the same event. A seizure is a change in the behavior as a result of abnormal electrical activity inside the brain. Manifestations of seizure can range from losing awareness or consciousness to wild shaking of the body. It […]

The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The nervous system has a specific sensory system or organ, dedicated to each sense. Humans […]

There are three theories of motor development maturation, information processing and the dynamic theory. The maturation theory focuses on the neurological factors that affect the development of motor skills, and is the term used to describe the innate sequences of physical changes (Macintyre and McVitty, 2004, pp 57). Whereas the information processing theory focuses on belief […]

Eysenck’s Personality Theory is primarily based on the operation of the Central Nervous […]
