Neuroimaging study sheds new light on how we perceive colors. Activity in higher visual cortex areas matched the colors test subjects saw.
A visual cortical prosthesis can restore sight by bypassing damage to the eyes and delivering visual information retrieved from a camera directly to the brain.
The strength of a person's mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person's ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.
Understanding how the brain decides what it should pay attention to is key to understanding how prediction plays a tole in autism.
A newborn's brain is more adult-like than previously assumed. Neuroimaging revealed much of the visual cortex scaffolding is in place, along with patterns of brain activity at 27 days of age, although it is not quite as strong as seen in adult brains.
The way neurons are structured, and the patterns they make can be used to explain how they behave and function. The findings have implications for creating intelligent robots.
A drug commonly prescribed for edema improves the symptoms for young children on the autism spectrum with no significant side effects. The drug, bumetanide, decreases the ratio of GABA to glutamate in the brain.
DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.
