Researchers have given rats the ability to "touch" infrared light by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes tactile information. The study demonstrated that a novel sensory input could be processed by a cortical region specialized in another sense without "hijacking" the function of this brain area.
Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.
Researchers discover an unexpected role for the visual cortex in promoting the plasticity of innate eye movements.
According to a new study, speech can be recovered on the right side of the brain following a stroke.
The size and shape of neural assemblies, and not the strength of signals processed by neurons or the order in which they fire, is the most critical element of recording episodic memory.
The naturally occurring insulin-like growth factor (IGF-II) improved memory and slowed forgetting in rats according to new research.
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.
