A/E are true propeies of spinal cord reflex :
A i.e. MemoryMemory is strictly a function of brain not seen in spinal cord reflexQ and sites where memory is stored are: neocoex, amygdala Q, some areas of corpus striatumQDelayQ- Between the application of stimulus & staing of the response there is a time -interval.- Most of the delay occurs at the synapse.FatigueQWhen a nerve is stimulated, flexor response appears within a few millisecond because of spinal reflex. Then in the next few seconds the reflex begins to fatigue.Summationc2: Two typesa) Temporal summation - A single subthreshold stimulus fails to produce a response two (or more) subthreshold stimuli, applied in quick succession, can evoke a response.b)Spatial summation - Two subthreshold stimuli, applied simultaneously but at different spots,- OcclusionQ- Subliminal fringeQ- IrradiationQ- Habituation & SensitizationQ
