Abstract Idling brain activity has been proposed to facilitate inference, insight, and innovative problem-solving. However, it remains unclear how and when the idling brain can create novel ideas. Here, we show that cortical offline activity is both

Increased levels of lactate, an end-product of glycolysis, have been proposed as a potential surrogate marker for metabolic changes during neuronal excitation. These changes in lactate levels can result in decreased brain pH, which has been implicate

Hippocampus as a sorter and reverberatory integrator of sensory inputs

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-15 (2022)

How the hippocampus sorts and integrates multiple sensory inputs during learning remains unclear. Here, the authors found that the hippocampus uses reverberatory activity to link conditioned and unconditioned stimuli and to avoid crosstalk during sen

A cortical cell ensemble in the posterior parietal cortex controls past experience-dependent memory updating

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-14 (2022)

Animals refer to related past experiences when processing sensory inputs. The authors show that a cellular ensemble in the posterior parietal cortex that is activated during past experience mediates an interaction between past and current information
