Week 5 Forum Student’s Name Institutional Affiliation Date The amygdala and hippocampus are the main parts of the brain whose responsibility is the regulation of memory. The amygdala is divided into two, the right and left hemispheres. The right hemisphere is responsible for negative emotions like fear and sadness while the left hemisphere induces both the pleasant and unpleasant emotions when stimulated. These hemispheres have independent memory systems but they work together to encode, store and interpret information. The hippocampus on the other side is responsible for the production of corticosteroids (chemicals that produce physiological responses to stimuli).
1.2 Describe the key functions of the brain that are affected by dementia. Within the brain there are nerve cells that are known as neurons. These neurons communicate with each other and with other parts of the body. The brain sends signals to the body and to other parts of the brain in the form of electrical impulses aided by neurotransmitters (chemical messengers. The chemical and electrical signals are necessary in controlling bodily functions – for example language, decision-making, memory, personality, behaviour, sensing and interpreting our environment, and controlling muscle movements.
A) The key functions that are affected by dementia are vision, memory, hearing, language and learning, which the temporal lobe (bottom left front lobe of the brain) is responsible for. Decision making, problem solving, control of behaviour and emotions, which the frontal lobe (front lobe of the brain) is responsible for, can also be affected. Sensory information form the body, letter forming, putting things in order and spatial awareness, which the parietal lobe (middle top lobe of the brain) is responsible for, can also be affected. Processing information related to vision, which the occipital lobe (back lobe of the brain) is responsible for, can also be affected. Memory, attention, thought, senses and movement, which the cerebellum lobe (right at the bottom of the brain next to the brain stem) is responsible for, can also be affected.
There are a number of cell junctions used by the various tissue types for contact with surrounding cells and the basement membrane, communication and for structural integrity. The contrast of the functions of each tissue is that some are striated and some are unstraited.

Understanding their different roles and functions, please describe what you think would happen to the body if each was damaged? If each membrane is damaged, the epithelium would not be able to be held up because the lamina propia is what supports the epithelium.
4. Describe the relationship between biological psychology and other fields in psychology and neuroscience. 5. Describe the major underlying assumptions of a biopsychological approach. 6.
If so, then how? The mind-body problem has basically two branches of thought. One branch is of the mind, in the sense of consciousness, studied by theology, philosophy, and psychology. The other branch is of the body which is biologically based. However, within these branches of thought lie many theories to the mind-body problem.
This form of psychology is involved with the mind-body dispute and researchers how they affect one another. Biological psychology thrives to explain the brain and the nervous system and how they relate to human characteristics such as learning, thinking, feeling, and perception. The biopsychological approach includes an assumption that biological events can cause mental consequences and vise versa. The main assumption is that the mental process and biological events are directly linked together and work as one. The history of biological psychology dates all the way back to the Greeks.
Nerve coverings—fibrous connective tissue * Endoneurium—surrounds individual fibers within a nerve * Perineurium—surrounds a group (fascicle) of nerve fibers * Epineurium—surrounds the entire nervea 4) Define the following parts of the brain & spinal cord. Your definition should include where the specific part is found, structure, function and any other information you feel is pertinent. 1) Brainstem- Consists of three parts of brain; named in ascending order: the medulla oblongata, pons, and midbrain- Structure—white matter with bits of gray matter scattered through it-Function—gray matter in the brainstem functions as reflex centers Heartbeat, respirations, and blood vessel diameter -Sensory tracts in the brainstem conduct impulses to the higher parts of the brain- Motor tracts conduct from the higher parts of the brain to the spinal cord 2) Diencephalon- Hypothalamus, a) Posterior pituitary gland, pituitary stalk, & gray matter b) Major center for controlling the ANS c) Functions of most internal
Hormones are thought to play a significant role in manipulating behavior and the mental process because they are involved in various mental disorders as a resulting in interacting with the nervous system. In conclusion, much theory and research have been placed on identifying the major schools of psychology and the underlining assumptions linked to biological factors of behavior. In the beginning stages of psychological research, psychology first began as an establishment of science separate from biology and philosophy. Within those complex findings began the debate in relation to the schools of thought and behavior in the human
& Mitterer, J. O., 2013). The temporal lobes also play a significant role in understanding language. It is important to understand that there are association areas in both lobes and it is these areas that combine and process information from the senses. So although there are specific areas where we know auditory information is processed, such as in the temporal lobes, or where motor functions are controlled, such as in the frontal lobes, the association areas make up the majority of these lobes. Which is why damage to any part of these areas on the left hemisphere of the brain can cause aphasia, which is having “impaired ability to use language” (Coon, D. & Mitterer, J. O.,
