HORROR-EVOKED AROUSAL AND AMYGDALA BIAS OF THE MEDIAL TEMPORAL LOBE
… memory. We measured neural circuitry in the medial temporal lobe (MTL), including the amygdala sub-nuclei areas of the basolateral and the central-medial amygdala, the anterior and posterior hippocampus, and the perirhinal cortex. We present neural univariate signals of these regions of …

Opioid induction of Fos in the female rat brain : modulation by ovarian hormones
… was analyzed in the lateral septum, medial preoptic area, ventromedial hypothalamus, medial amygdala, and mesencephalic central gray. The present study found that Fos immunoreactivity was induced differentially by the opioid agonists within the different brain regions, and the …

Naturally occurring variations in defensive burying behavior are associated with differences in central neuropeptide expression in the male rat
… of androgen receptor positive cells in the medial amygdala and posterior bed nuclei of the stria terminalis, brain regions that integrate emotional appraisal and sensory information. In contrast, animals showing little to no defensive burying responses expressed relatively higher levels of …

Photoperiodism in the ewe: Endogenous circannual rhythms and olfactory mechanisms influencing reproductive activity
… projection from the main olfactory bulb to the medial amygdala provides a potential mechanism whereby this structure may influence luteinizing hormone secretion.

Structural and Molecular Correlates of Individual Differences in Anxiety Behavior and the Stress Response
… and executive function; the hippocampus, amygdala and medial prefrontal cortex (mPFC). In the following experiments, we measured basal anxiety levels and compared anxiety behavior before and after stress. Individuals were grouped based on basal anxiety profiles (either "Calm" or "Anxious") …

CHARACTERIZATION OF TRANSMEMBRANE PROTEIN 35 EXPRESSION: CONSIDERATIONS OF SEX AND OVARIAN HORMONES
… high expression of TMEM35 in both the ventromedial hypothalamus (VMH) and the limbic circuit of the mouse brain. Due to the known functions of these two regions, this pattern of expression indicates possible roles of this neuropeptide in social behavior and reward processing. Interestingly, …

Role of the ventromedial hypothalamus in control of innate defensive behaviours
… the circuit controlling these behaviours. Ventromedial hypothalamus (VMH) is a key brain region for controlling responses to predators; it has been shown that inactivating the VMH can reduce defensive behaviours. Interestingly, activating the VMH output neurons (SF1+ cells) can produce a variety …

Dynamical Systems Analysis of Neural Circuits with Applications to Physiological Processes
… motivated by the role of the posterodorsal medial amygdala (MePD) as a key modulatory input to the GnRH pulse generator. We develop a biologically informed model of the MePD circuit to examine the role of interactions between glutamatergic and GABAergic neuronal populations in shaping …
