Long-term potentiation and long-term depression: a clinical perspective [PDF]

open access: yesClinics, 2011
Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system.

LTD at amygdalocortical synapses as a novel mechanism for hedonic learning

open access: yeseLife, 2020
A novel, pleasant taste stimulus becomes aversive if associated with gastric malaise, a form of learning known as conditioned taste aversion (CTA). CTA is common to vertebrates and invertebrates and is an important survival response: eating the wrong ...

Long-term course of severe depression: late remission and recurrence may be found in a follow-up after 38-53 years

open access: yesMental Illness, 2012
This study is a follow-up of inpatients diagnosed with severe depression/melancholia between 1956 and 1969. During this period, all inpatients at the Department of Psychiatry, University Hospital, Lund, were rated on a multidimensional diagnostic ...

Bidirectional Synaptic Plasticity Is Driven by Sex Neurosteroids Targeting Estrogen and Androgen Receptors in Hippocampal CA1 Pyramidal Neurons

open access: yesFrontiers in Cellular Neuroscience, 2019

Rho Signaling in Synaptic Plasticity, Memory, and Brain Disorders

open access: yesFrontiers in Cell and Developmental Biology, 2021
Memory impairments are associated with many brain disorders such as autism, Alzheimer’s disease, and depression. Forming memories involves modifications of synaptic transmission and spine morphology.

Delirium, depression, and long-term cognition

open access: yesInternational Psychogeriatrics, 2023
We examined whether preadmission history of depression is associated with less delirium/coma-free (DCF) days, worse 1-year depression severity and cognitive impairment.A health proxy reported history of depression. Separate models examined the effect of preadmission history of depression on: (a) intensive care unit (ICU) course, measured as DCF days ...

Stochastic Induction of Long-Term Potentiation and Long-Term Depression [PDF]

open access: yesScientific Reports, 2016
AbstractLong-term depression (LTD) and long-term potentiation (LTP) of granule-Purkinje cell synapses are persistent synaptic alterations induced by high and low rises of the intracellular calcium ion concentration ([Ca2+]), respectively. The occurrence of LTD involves the activation of a positive feedback loop formed by protein kinase C, phospholipase

Repetitive transcranial magnetic stimulation in psychiatry

open access: yesAnnals of Indian Academy of Neurology, 2011
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive and relatively painless tool that has been used to study various cognitive functions as well as to understand the brain-behavior relationship in normal individuals as well as in those ...

Peers, Gender, and Long-Term Depression [PDF]

open access: yesSSRN 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.
