The Role of PKC in Synaptic Plasticity

News   Jul 17, 2018 | Original Story from Max Planck Florida Institute for Neuroscience

Convergence of Synaptic Signals is Mediated by a Protein Critical for Learning and Memory

Model of integration of TrkB and calcium signals to induce PKCα activation in paired and unpaired subthreshold stimulations. A subthreshold stimulus that was unable to induce plasticity was given alone (unpaired) or after a nearby plasticity-inducing stimulation (paired). Unpaired, the stimulus could not activate PKCa or induce plasticity. However, when paired with recent plasticity in a nearby spine, which induces a long-lasting, spreading TrkB activity, this same subthreshold stimulus led to PKCa activation and plasticity.

Interference with Estrogen Signaling Sends Bone Formation into Overdrive


Deleting a certain type of estrogen receptor in an area of the hypothalamus dramatically increased bone density and strength in female mice, opening up many therapeutic possibilities for improving women's health.


Now Anyone Can Tour the Fly Brain


A new fly-through of the fly brain allows anyone to whizz past neurons and visit any of the 40 million synapses where neurons touch neuron. It’s a super-resolution view of the complex network connections in the insect’s brain that underlie behaviors ranging from feeding to mating.


Memories of Meals Influence Future Eating Behavior


Brain cells involved in memory play an important role after a meal in reducing future eating behavior, a finding that could be key in understanding and fighting obesity, according to a study led by Georgia State University.
