A Brain Filter for Clear Information Transmission

Frequently, as many as one thousand signals rain down on a single neuron simultaneously. To ensure that precise signals are delivered, the brain possesses a sophisticated inhibitory system. Scientists have now illuminated how this system works.

Entorhinal cortical neurons and traces are shown and described in the caption.

Researchers Discover that the Sleeping Brain Behaves as if it’s Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that the entorhinal cortex behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Discovery of Gatekeeper Nerve Cells Explains the Effect of Nicotine on Learning and Memory

Researchers discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can help explain our ability to remember and sort information. The newly discovered gatekeeper nerve cells, also called OLM-alpha2 cells, provide an explanation to how the flow of information is controlled in the hippocampus.
