Neurodegenerative Disease: What Potential Therapeutic Role of Acid-Sensing Ion Channels?
Frontiers in Cellular Neuroscience, 2021 Acidic pH shift occurs in many physiological neuronal activities such as synaptic transmission and synaptic plasticity but also represents a characteristic feature of many pathological conditions including inflammation and ischemia.

Temporal Map Formation in the Barn Owl’s Brain [PDF]
, 2001 Barn owls provide an experimentally well-specified example of a temporal map, a neuronal representation of the outside world in the brain by means of time. Their laminar nucleus exhibits a place code of interaural time differences, a cue which is used to

Learning to Discriminate Through Long-Term Changes of Dynamical Synaptic Transmission [PDF]
, 2008 Short-term synaptic plasticity is modulated by long-term synaptic changes. There is, however, no general agreement on the computational role of this interaction.

A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity
, 2012 In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...

SUMOylation of FOXP1 regulates transcriptional repression via CtBP1 to drive dendritic morphogenesis
Scientific Reports, 2017 Forkhead Box P (FOXP) transcriptional repressors play a major role in brain development and their dysfunction leads to human cognitive disorders. However, little is known about how the activity of these proteins is regulated.

Endoplasmic reticulum visits highly active spines and prevents runaway potentiation of synapses
Nature Communications, 2020 In hippocampal pyramidal cells, a subset of dendritic spines contain endoplasmic reticulum (ER). Here, the authors show that ER enters dendritic spines in a non-random manner, during high synaptic activity with the function of limiting synaptic strength.

Alterations in brain connectivity due to plasticity and synaptic delay
, 2017 Brain plasticity refers to brain's ability to change neuronal connections, as a result of environmental stimuli, new experiences, or damage. In this work, we study the effects of the synaptic delay on both the coupling strengths and synchronisation in a ...

Optimal storage and recall with biologically plausible synapses [PDF]
, 2011 Synaptic plasticity is widely accepted to underlie learning and memory. Yet, models of associative networks with biologically plausible synapses fail to match brain performance: memories stored in such networks are quickly overwritten by ongoing ...

Hebbian Wiring Plasticity Generates Efficient Network Structures for Robust Inference with Synaptic Weight Plasticity [PDF]
, 2016 In the adult mammalian cortex, a small fraction of spines are created and eliminated every day, and the resultant synaptic connection structure is highly nonrandom, even in local circuits.
