Paresis

Muscle Weakness

21

Rigidity

Increase in muscle tone meaning movement is restricted

22

Spasticity

Altered muscle performance die to paralysis

23

Neural Networks

A series of neurons which come together to create a linear pathway

24

Emergence

When neurones all work together to create a larger function e.g. consciousness

25

Hydrocephalus

The accumilation of CSF in the ventricles

26

Aneurysm

Abnormal dilatation of an artery

27

Stroke

An abrupt loss of brain function that lasts for more than 24 hours

28

Decussation

The crossing of neurones across the midline of the CNS

29

Lateral Inhibition

When interneurones inhibit their neighbouring neurones to localise sensation

30

Two Point Discrimination

The ability to tell the difference between two sensory inputs. The smaller the receptive field, the better the discrimination
