Document Summary
What important aspects about memory did we learn from the case study of patient. His anterior temporal lobe removed (cid:894)a(cid:373)(cid:455)gdala, hippo(cid:272)a(cid:373)pus, (cid:272)orte(cid:454)(cid:895). Each sensory system has a specific pathway and specific neurons. Neurons only respond to specific stimulus depending on what pathway they are a part of. Labeled lines and doctrine of specific nerve energies (sensory pathways are independent of each other). Labelled lines say that each sensory system has its own separate tract to the brain. The doctrine says that each sensory system is independent of each other: trace the pathway of sensory processing from the receptive field of the neuron up to the cortex. Receptor dorsal column of spinal dorsal medulla thalamus cortex. Touch: receptor to the dorsal column to the dorsal column nuclei in the medulla where it then crosses then to the thalamus to the sensory cortex.
