N. Katsuyama et al., LATERAL SUPRASYLVIAN VISUAL-CORTEX IS ACTIVATED EARLIER THAN OR SYNCHRONOUSLY WITH PRIMARY VISUAL-CORTEX IN THE CAT, Neuroscience research, 24(4), 1996, pp. 431-435
To explore functional connectivity between area 17 and posteromedial l
ateral suprasylvian (PMLS) area of the cat cerebral cortex, we carried
out cross-correlation analysis of spike trains of neurons recorded si
multaneously from both areas of anesthetized, paralyzed cat. Most of c
orrelated pairs had peaks which indicate that PMLS cells were activate
d earlier than or simultaneously with their partners in area 17, sugge
sting that 'backward' as well as synchronous activation operates betwe
en these cortical areas.
