Post myocardial infarction depression heightens long term mortality
Discover PsychologyMyocardial infarction (MI) is a leading cause of long-term morbidity and mortality, significantly impacting health-related quality of life. Post-MI depression is increasingly recognized as a critical comorbidity, associated with a 2- to 3-fold increased ...

Long-Term Depression of a Dopamine IPSC [PDF]
The Journal of Neuroscience, 2007 Two determinants of dopamine release from terminals in striatal and limbic structures are the pattern and rate of dopamine neuron firing in the ventral midbrain. This activity is regulated in part by somatodendritic release of dopamine and subsequent feedback inhibition through activation of D2receptors on dopamine neuron cell bodies and dendrites ...

Peers, Gender, and Long-Term Depression [PDF]
SSRN Electronic Journal, 2020 We provide first evidence that peer depression in adolescence affects own depression in adulthood. We use data from Add Health and an identification strategy that relies on within-school and across-cohort idiosyncratic variation in the share of own-gender peers who are depressed. We find a significant peer effect for females but not for males.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.

Modeling homosynaptic and heterosynaptic plasticity with a single neuromemristive synapse
Journal of Advanced ResearchIntroduction: Efforts are being made to design a brain-like intelligence due to its robustness, synaptic modification (i.e., learning and memory), analog synaptic multiplication, multi-state storage, ultra-low power consumption, and parallel computation.

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 ...

FEBS Open Bio, EarlyView.The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

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

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 ...
