Perception is the process by which the nature and meaning of sensory stimuli are recognized and interpreted. Perception can be influenced by attention and can occur subliminally, without conscious awareness.
The precise role that inferotemporal cortex plays in object recognition remains poorly understood. Here, the authors combine high-throughput behavioral optogenetics in non-human primates with machine learning to graphically capture perceptual events evoked by local stimulation in the high-level visual cortex.
Using stereotactic electroencephalography, the authors identified differential amygdala activation in response to emotional faces in participants with treatment-resistant depression compared with non-depressed participants with epilepsy, suggesting possible deep brain stimulation targets.
A mark test of self-recognition in mice reveals that self-responding ventral CA1 neurons underlie mirror-induced self-directed behaviour and are shaped by social experience with conspecifics.
Grid cells develop in rats soon after they leave the nest. Here, Ulsaker-Janke et al. show that preventing exposure to straight boundaries from birth delays, but does not prevent, grid cell maturation in adult rats.
The representational geometry of neural population activity in the somatosensory cortex of mice allows for high flexibility needed to perform complex tasks and for generalization to novel tasks at the same time.
Ketamine-induced dissociated states in mice result from the suppression and activation of cortical pyramidal neuron populations that are active and silent during wakefulness, respectively.
