Human perception of colors does not rely entirely on language

Based on the study of a stroke patient with damage to the occipito-temporal brain region, researchers made a big discovery about color categorization. They reveal color categorization and naming can be independent in the human brain. The finding challenges long-standing theories of the mandatory involvement of language in adult human cognition and color discrimination.

Deciphering how the brain encodes color and shape

Visual neurons selectively respond to color and shape along a continuum. While some neurons are only activated by either a specific color or shape, others are responsive to color and shape simultaneously. The findings contradict previous beliefs about how visual processing works.

Neurons’ “antennae” are unexpectedly active in neural computation

When the soma of specific neurons is active, the dendrites of the same neuron are also active, even when animals are not engaged in a cognitively demanding task.

Brain stimulation enhances visual learning speed and efficiency

Transcranial random noise stimulation (tRNS) helps boost visual learning in patients with chronic cortical blindness, leading to a recovery in motion processing within 10 days of exposure. The effects of the tRNS treatment appear to last for at least six months.

Developing a headset to transfer visual perceptions from the sighted to the blind

Researchers are developing a new brain-to-brain communication headset that will allow the transfer of visual information from those with sight to the blind. The non-invasive system will 'write' information to neurons reprogrammed to fire in response to magnetic signals.
