Techniques for Studying the Brain
Brain Lesioning, EEG, Brain Imaging, Trans cranial Magnetic Stimulation (TMS)
Measures electrical activity in the brain. A drawback is that it's not within the brain, only the outer layer.
Lesion or damage part of the brain and see what abilities the individual loses. (animals)
X-ray of the brain that provides a 3-D picture showing structure (doesn't show function) (Drawback: radiation exposure)
(Magnetic resonance imaging) generally shows structure. Draw on the magnetic properties in the body. (structure)
Trans cranial Magnetic Stimulation (TMS)
Creates a virtual lesion deactivating a part of the brain but only temporarily; newer technique, not brain imaging, a safe way to carry out brain liesoning
The most forward part of the brain and is considered the higher part of the brain and generally responsible to higher functions
related to experience of our emotions, especially survival emotions (anger, fear, aggression) (Amy; girls have emotions)
Responsible for the formation of memories (elephants & hippos because they have a good memory)
Part of the brain sensory relay station; sensory (except smell) info goes through here first and then directed to other parts of the brain (operator receiving and directing calls)
Involved in voluntary movements like habitual movements such as walking, typing, writings, etc.
Influences hunger, indirectly controls hormones; controls and influences hormones because it controls the pituitary glands (hunger & hormones)
The Cerebral Cortex
What sets humans apart from other animals; the outer layer of the brain; very integrated and always sharing information; divided into 2 hemispheres and 4 lobes
Primarily processes VISUAL information (visual cortex; responsible for the initial processing of visual information) (optical,eye,visual)
Processes LANGUAGES in general and contains the auditory cortex (initial processing of auditory information)
Processes space location; (clapping, moving around) where you are in space. Helps navigate where things are and how to get places; processes touch information
Throughout the cerebral cortex; integrates information (recognizes sounds and then deciding what to do)
Thick band of fibers connecting the hemispheres and allows for constant information.
