Are there certain locations for the processing of specific sensory, integrative and motor signals in the cortex?

Describe the basic pathway of information flow through neurons that causes you to turn your head when someone calls your name.

Describe how neurons communicate. To do this you must address: resting membrane potential; graded potentials; IPSPs; EPSPs; the role of sodium, potassium and calcium; generation of an action potential; inotropic vs metabutropic receptors; why is an AP only one direction; how are neurotransmitters released; continuous vs saltatory conduction; spatial vs temporal summation.

Upper motoneurons which are often affected in MND are originate from the       Primary motor cortex only     Somatosensory motor cortex only     Primary motor and pre motor cortices     Pre motor cortex only     Primary motor, pre motor and primary sensory cortices
