In the brain's secondary motor cortex, researchers have discovered two distinct maps that play a crucial role in spatial planning and navigation. The research, led by Dr. Jeffrey Erlich, Group ...

The authors examined neuronal activity in the lateral (AGl) and medial (AGm) agranular cortex, corresponding to the primary and secondary motor cortex, respectively, in rats performing a dynamic ...

The team knew from previous experiments that neuronal projections from the secondary motor cortex (M2) modulate the auditory cortex. But to isolate M2's relative contribution ...

The researchers confirmed that the movement signals came from the motor area of the brain by focusing on the secondary motor cortex. They surgically destroyed it in several rats, then ran the ...

However, the researchers were not able to determine if the signal originates in the secondary motor cortex. It could be only where it passes through, they said. Furthermore, the scientists pointed ...

The secondary motor cortex (M2) acted as a "sensory gatekeeper." When the mice were moving, M2 sent inhibitory signals to the auditory cortex, blocking auditory signals from reaching the PPC.

Optogenetic stimulation of M2 cortex terminals in the SC evoked similar electrophysiological responses in WT and HD mice. A, Schematic representation of AAV-CamKII-ChR2-YFP construct injection at ...

The results of the study are published in Neuron, in the article, “Encoding of 3D Head Orienting Movements in the Primary Visual Cortex.”The findings suggest that image-processing circuits in ...

A new study has suggested that head movement and sight are more closely linked than though, with researchers describing two sets of movement-related patterns in the visual cortex of the brain.
