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 |
