Long-term habituation of the gill-withdrawal reflex in Aplysia requires gene transcription, calcineurin and L-type voltage-gated calcium channels

Frontiers in Behavioral Neuroscience, 2010
Although habituation is possibly the simplest form of learning, we still do not fully understand the neurobiological basis of habituation in any organism.

Long-term obesity is associated with depression and neuroinflammation [PDF]

Archives of Endocrinology and Metabolism, 2021
Obesity is characterized by a state of chronic, low-intensity systemic inflammation frequently associated with insulin resistance and dyslipidemia.Given that chronic inflammation has been implicated in the pathogenesis of mood disorders, we investigated if chronic obesity that was initiated early in life - lasting through adulthood - could be more ...

TIME OF DIABETIC ULCER FOOT SUFFERING AND DEPRESSION SYMPTOMS IN ULIN GENERAL HOSPITAL BANJARMASIN

Berkala Kedokteran, 2017
: Diabetic foot ulcers are one kind of chronic complication of diabetes mellitus in the form of an open wound on the skin’s surface and may be accompanied by local tissue death.  Long term suffering of diabetic foot ulcers with physical and psychological

Motor cortical plasticity induced by motor learning through mental practice.

Frontiers in Behavioral Neuroscience, 2015
Several investigations suggest that actual and mental actions trigger similar neural substrates. Motor learning via physical practice results in long-term potentiation (LTP)-like plasticity processes, namely potentiation of M1 and a temporary occlusion ...

The demise of the synapse as the locus of memory: A looming paradigm shift?

Frontiers in Systems Neuroscience, 2016
Synaptic plasticity is widely considered to be the neurobiological basis of learning and memory by neuroscientists and researchers in adjacent fields, though diverging opinions are increasingly being recognised. From the perspective of what we might call

Spike timing dependent plasticity: a consequence of more fundamental learning rules

Frontiers in Computational Neuroscience, 2010
Spike timing dependent plasticity (STDP) is a phenomenon in which the precise timing of spikes affects the sign and magnitude of changes in synaptic strength.

A Practical Guide to Using CV Analysis for Determining the Locus of Synaptic Plasticity

Frontiers in Synaptic Neuroscience, 2020
Long-term synaptic plasticity is widely believed to underlie learning and memory in the brain. Whether plasticity is primarily expressed pre- or postsynaptically has been the subject of considerable debate for many decades. More recently, it is generally

Reversing cerebellar long-term depression [PDF]

Proceedings of the National Academy of Sciences, 2003
The discovery of a postsynaptically expressed form of cerebellar parallel fiber–Purkinje cell long-term potentiation (LTP) raises the question whether this is the long-sought resetting mechanism for long-term depression (LTD). Extracellular monitoring of PC spikes enables stable prolonged recordings of parallel fiber–Purkinje cell synaptic

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

Population Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...
