HUMAN BRAIN The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The human brain is the command centre for the human nervous system. It receives input from the sensory organs and sends output to the muscles. Parts of the Human Brain Ventricles are the 4 cavities in the brain. • The ventricles of the brain are a communicating network of cavities filled with cerebrospinal

THE BIOLOGY OF MIND Chapter 2 SQ3R (Survey‚ Questions‚ Read‚ Retrieve‚ Review) QUESTIONS: BIOLOGY‚ BEHAVIOR‚ AND MIND 2-1: Why are psychologists concerned with human biology? By studying the links the behavior and biology‚ psychologist work from a biological perspective. This perspective shows the psychologist which areas of systems interact to influence behavior. Humans are biopsychosocial systems‚ in which biological‚ psychological‚ and social-cultural factors interact to influence our

Chapter 2 Outline The Biological Perspective Neuron A specialized cell transmitting nerve impulses; a nerve cell Dendrites Dendrites are treelike extensions at the beginning of a neuron that help increase the surface area of the cell body and are covered with synapses Soma The soma is the cell body of a neuron. Axon The Axon of a neuron is a singular fiber that carries information away from the soma to the synaptic sites of other neurons (dendrites and somas)‚ muscles‚ Glial

The biological approach asserts that something in our biology is the fundamental cause of dysfunctional behaviour which could be a genetic cause or a malfunction of brain structures. Although it is seen as the most common explanation for schizophrenia due to the use of drug therapy‚ it would be deterministic and reductionist to explain schizophrenia only with the biological approach since there are other numerous factors such as the ones related to the cognitive explanation or other environmental

Dementia Awareness Task A 1) The term ’dementia’ describes a set of symptoms that include loss of memory‚ mood changes‚ and problems with communication and reasoning. There are many types of dementia. The most common are Alzheimer’s disease and vascular dementia. Dementia is progressive‚ which means the symptoms will gradually get worse. 2) Examples of different types of dementia are: Alzheimer’s disease‚ Vascular dementia‚ Dementia with Lewy bodies‚ Parkinson’s disease‚ Frototemporal dementia

recognizing faces. The specific area of the brain responsible for this disorder is the fusiform gyrus which is part of the temporal lobe. It is also called the occipitotemporal gyrus. Researchers infer then that the problem has something to do with the fusiform gyrus itself or in the neural pathways that convey information from that area to other parts of the brain‚ like the occipital lobe‚ which processes visual information. so‚ prosopagnosics usually rely on voice‚ style of walking‚ hairstyle‚ clothing
