Progressive overfilling of readily releasable pool underlies short-term facilitation at recurrent excitatory synapses in layer 2/3 of the rat prefrontal cortex

The paper investigates short-term facilitation at excitatory synapses in the rat prefrontal cortex, identifying Ca2+- and Syt7-dependent mechanisms that contribute to temporal associative learning.

Prelimbic corticopontine neurons gate extinction learning

This study identifies a mechanism by which prelimbic corticopontine neurons gate extinction learning through mitochondria-dependent post-tetanic potentiation.

Molecular Basis of Kv1 Channel Downregulation and Its Epileptogenic Implications in Lgi1 Knock-out Mice

This study investigates Kv1 channel downregulation in LGI1 knock-out mice, showing it occurs in somatodendritic regions and is linked to increased neuronal bursting and changes in the Kv1 interactome.

Input-specific bi-directional regulation of CA3 pyramidal cell excitability: its implications in sequence learningn

The paper investigates how CA3 pyramidal cell excitability is regulated by mossy fiber and perforant pathway inputs, showing their role in sequence learning through bidirectional regulation of excitability and synaptic plasticity.

Voltage-gated calcium channels contribute to spontaneous glutamate release directly via nanodomain coupling or indirectly via calmodulin

The paper investigates whether voltage-gated calcium channels (VGCCs) contribute to spontaneous glutamate release, finding that coupling distance and calmodulin influence this contribution in different synapses.

Calbindin regulates Kv4.1 trafficking and excitability of dentate granule cells via CaMKII-dependent phosphorylation

This study shows calbindin regulates Kv4.1 trafficking and neuronal excitability via CaMKII-dependent phosphorylation, linking Ca2+ buffering to neuronal function.

Impaired pattern separation in Tg2576 mice is associated with hyperexcitable dentate gyrus caused by Kv4.1 downregulation

This study shows that Tg2576 mice exhibit impaired pattern separation linked to hyperexcitable dentate gyrus due to Kv4.1 downregulation, which is reversible with antioxidant treatment.
