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
