Schizophrenia is a category of mental illness of the psychotic disorders. Psychosis refers to specific abnormalities of cognition that include delusions and hallucinations. The abnormalities of Schizophrenia are often divided into 3 categories. The first being cognitive which deals with abnormalities of attention and planning abilities. The second category of abnormalities of Schizophrenia is often called negative symptoms which can include blunted emotions and a loss of enjoyment. The third category

assumed to be more intelligent than ‘lower’ mammals‚ the great apes and humans more than monkeys‚ and humans more than the great apes. Brain properties assumed to be relevant for intelligence are the (absolute or relative) size of the brain‚ cortex‚ prefrontal cortex and degree of encephalization. However‚ factors that correlate better with intelligence are the number of cortical neurons and conduction velocity‚ as the basis for information-processing capacity. Humans have more cortical neurons than other

2014 The temporal lobe is a region of the cerebral cortex that is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. The temporal lobes are involved in the retention of visual memories‚ processing sensory input‚ comprehending language‚ storing new memories‚ emotion‚ and deriving meaning. The frontal lobe is an area in the brain of mammals‚ located at the front of each cerebral hemisphere and positioned anterior to (in front of) the parietal

In this activity you will take a tour of the human brain and explore the major brain regions to discover the functions of each region or area. Functional Specialization • In terms of brain function‚ what is functional specialization? Hearing a sound or moving our thumb is controlled by a cluster of neurons. This gives us the capability of the nervous system. A neural network is the cluster of neurons. • Why is the principle of complex communication important to understand? Each neural

primary motor cortex from the primary somatosensory cortex. It is a prominent landmark of the brain. The lateral sulcus divides both the frontal and parietal lobe above from the temporal lobe below. The lateral sulci are also known as the fissure of Sylvius and the central sulci is also referred to as fissure of Rolando. The folds created by the sulci increase the amount of cerebral cortex that can fit in the skull‚ in other words the surface area. Basal Nuclei and Cerebral Cortex Fibrils The term

BRAIN AND BEHAVIOR Functional Specialization • In terms of brain function‚ what is functional specialization? Functional specialization is the function of the nervous system. Each of the neurons located within the nervous system are grouped into clusters‚ these clusters have a specific purpose in the body’s function. Such as movements of the limbs‚ emotions‚ memory and bodily functions. • Why is the principle of complex communication important to understand? The principle of complex
