Navigation brain cells in retrosplenial cortex preserved across evolution
Researchers found two special neuron types in the retrosplenial cortex that help navigation. These cells are conserved between mice and rats, linked to spatial disorientation in Alzheimer’s, and are now being studied in humans.

Sensory Brain Areas Support Speech Memory
A study tested which brain systems keep newly learned speech movements. Disrupting sensory brain areas (auditory or somatosensory) reduced memory for the new speech, while disrupting the motor area did not. The finding may help speech rehabilitation.
