A novel instructive role for the entorhinal cortex discovered – ScienceDaily
Quoting some interesting parts from the article:
For more than 70 years, Hebbian theory which is colloquially summarized as, “neurons that fire together, wire together,” singularly dominated the neuroscientists’ view of how synapses become stronger or weaker over time. While this well-studied theory is the basis of several advancements in the field of neuroscience, it has some limitations. In 2017, researchers in the Magee lab discovered a new and powerful type of synaptic plasticity – behavioral timescale synaptic plasticity (BTSP) – which overcomes these limitations and offers a model that best mimics the timescale of how we learn or remember related events in real life.
I just realized there was more than just Hebbian learning going on in the brain. There are also STDP-like learnings going on, too. And now add BTSP to the mix.
“The discovery that one part of the brain (entorhinal complex) can direct another brain region (hippocampus) to alter the location and activity of its neurons (place cells) is an extraordinary finding in neuroscience,”
