Advanced Science, EarlyView.The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Amygdala fMRI—A Critical Appraisal of the Extant Literature
Neuroscience InsightsEven before the advent of fMRI, the amygdala occupied a central space in the affective neurosciences. Yet this amygdala-centred view on emotion processing gained even wider acceptance after the inception of fMRI in the early 1990s, a landmark that ...

MEG evidence for dynamic amygdala modulations by gaze and facial emotions.
PLoS ONE, 2013 BackgroundAmygdala is a key brain region for face perception. While the role of amygdala in the perception of facial emotion and gaze has been extensively highlighted with fMRI, the unfolding in time of amydgala responses to emotional versus neutral ...

AGING MEDICINE, EarlyView.Foreign language learning in older adults reorganizes thalamic and caudate connectivity, in a process topographically overlapping with the expression of receptors and genes related to neuroplasticity. ABSTRACT Objectives Neuroimaging studies suggest that Foreign Language Learning (FLL) influences resting‐state functional connectivity (rs‐FC) within the

Robust automated amygdala segmentation via multi-atlas diffeomorphic registration
Frontiers in Neuroscience, 2012 Here, we describe a novel method for volumetric segmentation of the amygdala from MRI images collected from 35 human subjects. This approach is adapted from open-source techniques employed previously with the hippocampus (Suh et al., 2011; Wang et al ...

The alpha1 subunit of the GABA(A) receptor modulates fear learning and plasticity in the lateral amygdala. [PDF]
, 2009 Synaptic plasticity in the amygdala is essential for emotional learning. Fear conditioning, for example, depends on changes in excitatory transmission that occur following NMDA receptor activation and AMPA receptor modification in this region.

Alcohol dependence potentiates substance P/neurokinin-1 receptor signaling in the rat central nucleus of amygdala. [PDF]
, 2020 Behavioral and clinical studies suggest a critical role of substance P (SP)/neurokinin-1 receptor (NK-1R) signaling in alcohol dependence. Here, we examined regulation of GABA transmission in the medial subdivision of the central amygdala (CeM) by the SP/

Reduced CB1 Cannabinoid Receptor Expression in Alzheimer's Disease and Transgenic Mouse Models
AGING MEDICINE, EarlyView.CB1 receptor (CB1R) expression was significantly reduced in the hippocampus, medial frontal gyrus, and superior temporal gyrus of Alzheimer's patients. CB1R levels negatively correlated with amyloid‐β and tau pathology. In addition, CB1R expression was also reduced in the cortex of 5xFAD mice and in the hippocampus of Tg4‐42 mice.

Beta-Adrenergic Receptor Blockade By Propranolol Enhances Retention In A Multitrial Passive-Avoidance Procedure [PDF]
, 2000 The effect of beta -adrenergic receptor blockade on retention in a mildly aversive passive-avoidance procedure was investigated. Rats were given passive-avoidance training-1 trial per day for 4 days-and were administered saline, the centrally and ...
