Document Summary

Dorsal: refers to the back of the axis. Ventral: to the front of the axis or to the belly . Rostral: toward the top of the axis. Caudal: towards the bottom of the axis. Medial: locations in the brain that are more central or towards the midline of the brain. Lateral: regions towards the outside of the brain. In such ablation studies, a researcher destroys, removes or inactivates a defined brain region and observes the result on behaviour. The accuracy of this emerging understanding of structure and function can depend on the precision of the lesion. The pattern of firing reveals a particular neuron"s functional role. In a typical experiment, cats were presented with specific visual stimuli while recording from single cells in the visual cortex. In this way, individual cell types were identified that responded to specific categories of visual stimuli. A major limitation with the ct scan by today"s standards is its relatively low resolution.
