Nervous System
A system of networks of neurons that connect different parts of the body to each other and the brain to electrochemical signals
The nervous system
The left hemisphere controls the right side of the body, and the right hemisphere controls the left side of the body
Contralateral
The specific research design used when researching Phineas Gage
Case study
Records electrical activity of the brain using electrodes on the scalp
EEG
This research design allows a causal relationship to be established between variables.
Experimental (research)
Sensory and motor
The branches of the somatic nervous system?
This part of the brain transfers information registered in one hemisphere to the other hemisphere for processing
The corpus callosum
The researcher on your syllabus associated with pre-frontal lobotomies.
Walter Freeman
Uses X-rays taken from different angles to create cross-sectional images of the brain.
CT/CAT
This method of sampling involves recruiting participants through referrals from other participants.
Snowball
This connects the brain to the peripheral nervous system
The spinal cord
The lobe of the brain that is involved with body sensations/tactile sensations
Parietal
Roger Sperry was associated with research in this area (syllabus terms required).
Split brain studies
fMRI provides both structural and this additional type of brain information
The extent to which the results of a study can be generalised.
External validity
The division of the peripheral nervous system that transmits sensory information received from receptor cells inwards towards the central nervous system, and motor messages from the central nervous system to the body’s voluntary skeletal muscle
The somatic nervous system
The most anterior/forward part of the frontal lobe and the most evolved area of the brain.
Pre-frontal cortex
The name of the ice pick tool Freeman used in his surgeries.
Leukotome
Uses strong magnets and radio waves to create detailed images of brain structures
MRI
It provides rich detailed data but can be difficult to statistically analyse.
Qualitative
Examples of this part of the nervous system activating could be decreased heart rate, pupil constriction, decreased blood pressure.
The parasympathetic nervous system?
True or False - a feature of Broca's Aphasia where patients may be limited to ‘telegraphic’ statements (words like ‘is’ or ‘the’ are left out).
True
The condition that a 'split brain' is used to cure.
What is epilepsy?
A limitation of MRI is that it is not suitable for patients with these type of implanted devices?
Metal
A non-experimental study designed to measure the degree of relationship two existing traits, behaviours or events.
Correlational
