Magnocellular pathway vs parvocellular
Web19 jul. 2007 · We used the framework of the magnocellular (M) and parvocellular (P) visual pathways. M pathways (transient channels) respond to small luminance changes, low spatial frequencies (coarse resolution of objects), and to rapid temporal changes (brief stimulus exposure and fast offset). WebHere we investigate the correlation between the expression of T-channel coding genes (alpha1G, -H, -I), T-type Ca(2+) current, and the T-current-dependent low threshold Ca(2+) spike in three functionally distinct thalamic nuclei (lateral geniculate nucleus; centrolateral nucleus; reticular nucleus) in a rat model of absence epilepsy, the WAG/Rij rats, and a …
