Table of electrophysiological landmarks

Landmarks (Fig. 7)	Electrophysiological feature
Brain surface/ventricle	Lack of spiking activity and reduced LFP power in saline or CSF compared with the brain
Fiber tract	Reduced activity and smaller spike amplitude compared with cortical regions
CA1 pyramidal cell layer	Higher activity and larger amplitude spikes than other parts of the hippocampus; LFP phase inversion
Hippocampus to thalamus boundary	Higher activity and spike amplitude in thalamic nuclei than hippocampus
Transition from arbor vitae to deep cerebellar nuclei	Higher activity and larger spike amplitude in the deep cerebellar nuclei
Medial superior olive	Sound related-activity in auditory tasks
Gray matter to white matter transition in the cerebellum	Reduced activity and lack of units in the white matter compared with the gray matter
Transition from the vestibular nucleus to other parts of the medulla	Higher spiking activity of neurons in the vestibular nucleus compared with other parts of the medulla
