Persistent activity in a recurrent circuit underlies courtship memory in Drosophila

eLife, 2018
Recurrent connections are thought to be a common feature of the neural circuits that encode memories, but how memories are laid down in such circuits is not fully understood.

ADAR-mediated RNA editing suppresses sleep by acting as a brake on glutamatergic synaptic plasticity. [PDF]

, 2016
It has been postulated that synaptic potentiation during waking is offset by a homoeostatic reduction in net synaptic strength during sleep. However, molecular mechanisms to support such a process are lacking. Here we demonstrate that deficiencies in the

Application of artificial synapse based on all-inorganic perovskite memristor in neuromorphic computing

Nano Materials Science
Artificial synapse inspired by the biological brain has great potential in the field of neuromorphic computing and artificial intelligence. The memristor is an ideal artificial synaptic device with fast operation and good tolerance.

Short-term plasticity of the motor cortex compensates for bradykinesia in Parkinson’s disease

Neurobiology of Disease, 2023
Patients with Parkinson's disease (PD) show impaired short-term potentiation (STP) mechanisms in the primary motor cortex (M1). However, the role played by this neurophysiological abnormality in bradykinesia pathophysiology is unknown.

Kibra Anchoring the Action of PKMζ Maintains the Persistence of Memory [PDF]

How can short-lived molecules selectively maintain the potentiation of activated synapses to sustain long-term memory? Here, we find kidney and brain expressed adaptor protein (KIBRA), a postsynaptic scaffolding protein genetically linked to human memory

Tensor coupling and relativistic spin and pseudospin symmetries with the Hellmann potential [PDF]

arXiv, 2012
The Hellmann potential is a superposition potential that consists of an attractive Coulomb potential and a Yukawa potential. By using the generalized parametric Nikiforov-Uvarov (NU) method, we have studied the approximate analytical solutions of the Dirac equation with the Hellmann potential including a Coulomb-like tensor potential for arbitrary spin-

Phenomenological Potential Wells for C60 Shell [PDF]

arXiv, 2014
A spatial distribution of electric charges forming a square potential well has been studied. It is shown that this potential is created by two spherical double charge layers, which is in contradiction with a real molecular structure of C60 cage. A C60 shell potential has been calculated in the assumption that it is formed by the averaged charge density
