Brain's internal compass also navigates during imagination

Brain's internal compass also navigates during imagination | Neuroscience Research | Scoop.it
When you try to find your way in a new place, your brain creates a spatial map that represents that environment. Neuroscientists now show that the brain’s ‘navigation system’ is not only active during actual or virtual movement, but also when imagining view directions. This suggests that the brain’s spatial navigation system might also be important for cognitive functions such as imagination and memory.

Researchers discover how and where imagination occurs in human brains

Researchers discover how and where imagination occurs in human brains | Neuroscience Research | Scoop.it
Philosophers and scientists have long puzzled over where human imagination comes from. In other words, what makes humans able to create art, invent tools, think scientifically and perform other incredibly diverse behaviors?

Whole-brain functional imaging at cellular resolution using light-sheet microscopy

Whole-brain functional imaging at cellular resolution using light-sheet microscopy | Neuroscience Research | Scoop.it

Brain function relies on communication between large populations of neurons across multiple brain areas, a full understanding of which would require knowledge of the time-varying activity of all neurons in the central nervous system. Here we use light-sheet microscopy to record activity, reported through the genetically encoded calcium indicator GCaMP5G, from the entire volume of the brain of the larval zebrafish in vivo at 0.8 Hz, capturing more than 80% of all neurons at single-cell resolution. Demonstrating how this technique can be used to reveal functionally defined circuits across the brain, we identify two populations of neurons with correlated activity patterns. One circuit consists of hindbrain neurons functionally coupled to spinal cord neuropil. The other consists of an anatomically symmetric population in the anterior hindbrain, with activity in the left and right halves oscillating in antiphase, on a timescale of 20 s, and coupled to equally slow oscillations in the inferior olive.

A Brain-to-Brain Interface for Real-Time Sharing of Sensorimotor Information

A brain-to-brain interface (BTBI) enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats. In this BTBI, an “encoder” rat performed sensorimotor tasks that required it to select from two choices of tactile or visual stimuli. While the encoder rat performed the task, samples of its cortical activity were transmitted to matching cortical areas of a “decoder” rat using intracortical microstimulation (ICMS). The decoder rat learned to make similar behavioral selections, guided solely by the information provided by the encoder rat's brain. These results demonstrated that a complex system was formed by coupling the animals' brains, suggesting that BTBIs can enable dyads or networks of animal's brains to exchange, process, and store information and, hence, serve as the basis for studies of novel types of social interaction and for biological computing devices.
