The biological bases of behaviour: Brain
Looking inside the brain: research methods
Electrical Recordings
EEG: a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp
Electrical stimulation of the brain
ESB: sending weak electric current into a brain structure to stimulate it. brain behaviour relationships
Used in brain surgeries
Transcranial Magnetic Stimulation
permits scientists to temporarily enhance or depress activity in a specific area of the brain
Brain-imaging procedures
CT scan- the brain structure
PET- brain and behaviour relation
MRI
fMRI
The brain and behaviour
The hindbrain
cerebellum and two structures found in the lower part of the brainstem; medulla and pons
Medulla- attacheds to the spinal cord, unconscious part
Pons- "bridge" connects brain stem with cerebellum
Cerebellum- coordination and movement
Midbrain
segment of the brainstem that lies between the hindbrain and the forebrain
The Forebrain: largest complex part of brain
The thalamus- sensory information must pass to get to the cerebral cortex
Hypothalamus: regulation of basic biological needs
Limbic system: centre of emotion
loosely connected network of structures located roughly along the border between the cerebral cortex and deeper subcortical areas
The Cerebrum: centre of complex thought
made up of the cerebral cortex, cerebral hemispheres, and corpus callosum
Right and Left brain: Cerebral Laterality
Bisecting the brain: split- brain research
Split brain surgery- bundle of fibres that connects the cerebral hemispheres is cut to reduce the severity of epileptic seizures
each hemisphere's primary connections are to the opposite side of the body
Hemispheric specialization in the intact brain
perceptual asymmetries- left-right imbalances between the cerebral hemispheres in the speed of visual or auditory processing
