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.
1. a) What are the parts of a neuron? - The parts of a neuron are dendrites, axons, the cell body, the terminal branches and myelin sheath. b) How are neural impulses generated? - Neural impulses are generated when a brief electrical charge travels down the spine. c) How does one nerve cell communicate with another?
Additionally he identified that different regions of the brain interact or work together to enable a process. Thus leading to his findings that loss of speech can arise from damage to the front half of the brain Schiller, 1979, cited in Toates, (2010). Geschwind (1972), cited in Toates, (2010), also found that brain regions interact to enable the performance and understanding of speech. His evidence came from an experiment that entailed a participant listening to a sentence and then repeating it. Geschwind concluded that brain interactions were necessary to carry out the instructions.
Emotions define who we are to ourselves, as well to others. They are the central core of psychiatric disorders and can change our physical well-being. Emotional experiences can leave strong traces in the brain, either good or bad. Scientists once thought that memories would only go to one system in the brain. But they have discovered that there are various ways for memories to be formed.
Further analysis into the cognitive functions and the brain was needed in order to understand what was going on. Before one understands how Gage’s accident support cognitive function, one must first have a clear understanding what cognition means (Hernandez, 2008). Cognition basically refers to brain functions that are high-leveled; also including the capability to retain information and learn. Being able to problem solve, focus, organize and to essentially be able to speak and accurately identify the environment that one is in (Hernandez, 2008). A common effect of frontal lobe damage can cause a remarkable change in one’s behavior socially.
Normal aggressive behaviour involves an interaction of a system of structures, as opposed to being dependent on separate brain structures. One part of this system is the Amygdala. This is a structure inside the temporal lobe which, plays an important role in the mediation of affective activities and on the expression of mood; mainly fear, rage and aggression. The amygdala is connected to many structures in the brain including the hippocampus, thalamus and pre frontal cortex. It is fundamental for self-preservation as it enables the identification of danger; therefore exhibiting clear links to aggression.
3. Controlled Variables are the temperature and stimulation voltage. 4. What structure was stimulated to cause a muscle contraction? The motor unit was stimulated 5.
Hormones cause cells to activate and once activated, the cells must have a receptor spot for the hormone. There are many emotions and hormonal functions affected by hormones such as puberty, character traits, a
Each hemisphere of a person’s brain can processes the opposite side of the body. This means that the right side of the brain has control over the left side of the body and can see what is being processed through the left eye, while the left side of the brain controls the right side of the body and can see what is being processed through the right eye. Very confusing yes, but that is how the brain works. A look into the way that the left brain and the right brain function will shed light on the impact they have on learning. Left brain learners and right brain learners are very different and prefer to learn in different styles and different environments.
The NLP Communication Model Neuro-Linguistic Programming (NLP) is about the ability to discover and change the way we communicate (internally, with ourselves, and externally, with others) in order to achieve our specific and desired outcomes. The NLP communication model is based on cognitive psychology and was developed by John Grinder and Richard Bandler. According to the NLP communication model, when someone behaves in a certain way (their external behaviour), a chain reaction is set up within you (your internal response), which in turn causes you to respond in some way (your external behaviour), which then creates a chain reaction within the other person (their internal response), and the cycle continues. The internal representations that we make about an outside event are not necessarilythe event itself.Typically, what happens is that there is an external event and we run that eventthrough our internal processing. We make an Internal Representation (I/R) of thatevent.
