Neuromodulators

Definition

 

 

 

 

Chemical messengers produced by neurons that act in a paracrine manner

Term

 

 

 

 

 

Neurohormones

Definition

 

 

 

 

Chemical messenger produced by a neuron, acts as a true hormone

Term

Focal seizure

Definition

 

 

 

 

Spontanious discharge of prosencephalic neurons accompanied by no spread as seen on EEG only

Term

 

 

 

 

Partial seizure

Definition

 

 

 

Focal seizure of limited spread seen clinically with or without loss of consiousness
