Human Brain
• Organ that is the basis of what persons sense, do, feel, and think
• sensory, behavioral, affective, and cognitive experiences and attributes
***each one has its own abstract concept of
MIND
• The BRAIN provides the physical substrate for the mind, and malfunction of the parts of the brain can lead to disorders of mental activity and behavior

representation  but for those with pathology they have disorder regarding the association area e.g. hearing about anatomy (thinks about fishball) and because of this association area you will be motivated to move e.g what
I am saying now is important
A chronic condition characterized by a progressive degeneration of neurons of the brain.
In some finding such that the neural density in the visual cortex is decreased patients with Schizophrenia have poor eye tracking or poor eye contact.
- Electrical stimulation of some areas may cause visual hallucinations and illusions
- Visual agnosia may occur when there is disruption of connection of visual cortex from temporal lobe

consists of the primary somatosensory (somesthetic)

The extent of each body part over the cortex corresponds with the degree of motor control over each of the represented parts

Limbic System
• Papez Circuit
•

Hippocampus, fornix, mamillary

bodies, anterior nucleus of the thalamus, and the cingulate gyrus
***Hippocampus- controls our emotions, related to anxiety and depression, in memory along with sleep transfer short term memory to long term memory.
• Boundaries
• Amygdala, septum, basal forebrain, nucleus accumbens, and orbitofrontal cortex ***orbitofrontal cortex controls most of the impulses so that we are not very impulsive
• Appears to house the emotional association areas, which direct the hypothalamus to express the motor and endocrine components of the emotional state
*Amygdala
• Critically important gate through which internal and external stimuli are integrated
***what are filtering through our senses they go to the amygdala and would sense it if it is something beneficial

to you, gives meaning to what you are understanding, what you are seeing, tasting or getting from your environment. • Information from the primary senses
