Brainstem cholinergic modulation of the limbic learning circuit
… neuronal activity (TIA) develops in the limbic (anterior and medial dorsal) thalamic nuclei and cingulate cortex as rabbits learned to locomote after a foot-shock predictive tone (CS+) and to ignore another tone (CS$-$) not predictive of shock (Gabriel et al., Behav. Brain Res., 1991, 46, …

Hippocampal modulation of cingulate cortex and limbic thalamus during learning
A characteristic of the cingulo-thalamic or the subicular thalamic pathway had been investigated during the discriminative avoidance conditioning in which a CR of stepping in an activity wheel prevents a footshock 5 sec. after an auditory CS+. Enhanced neuronal discharges in the mediodorsal (MDN) …

The association of limbic system activation with dream, bad dream and nightmare generation
… generation, with a particular focus on the limbic system. High versus low levels of limbic activation and its effect on the frequency of dream, bad dream, and nightmare recall, characteristics, and content were investigated using retrospective and prospective measures. Psychosocial stress – …

Vulnerability to cognitive, neurotoxic and neuroinflammatory effects of toxins that induce Parkinson's disease after administration of amphetamine-related drugs in mice
… a toxin known to induce PD in humans, in motor, limbic and cortical areas, and consequently affects cognitive performance. Mice received MDMA (10 mg/kg, twice a day/a week) for 9 weeks, followed by MPTP (20 mg/kg × 4 administrations), starting 2 weeks after MDMA discontinuation. Activation of …

Anatomy of visual hallucinations and fluctuations of consciousness in Lewy body diseases
… first the intralaminar and then the medial limbic thalamic nuclei across the spectrum of Lewy body diseases. Atrophy of these nuclei, atrophy of neurons, neuronal death and a-synuclein deposition were assessed and relationships with clinical variables tested. These studies found changes in …

Bridging the link between trauma, brain development and depression: epigenetic mechanisms
… We studied differences in the fronto-limbic system (a collection of areas responsible for emotion regulation) and methylation at the serotonin transporter (SLC6A4) and FK506 binding protein gene (FKBP5) genes (two genes strongly linked to stress regulation and depression). Second, how …

CHOLINERGIC CONTRIBUTIONS TO EMOTION REGULATION
… hydrochloride, which selectively activates limbic regions in humans and animals. Procaine has a high affinity for muscarinic cholinergic receptors in vitro. This research tests three hypotheses: (1) procaine binds to muscarinic receptors in vivo; (2) procaine alters functional connectivity …

THE ROLE OF TRIGEMINAL ISL1 NEURONS IN FEEDING BEHAVIOUR
… of the activity of ISL1MoV and MoV projecting limbic neurons in feeding assays revealed changes to the feeding patterns of mice. Additionally, the effects of neural transmission of inhibitory limbic neurons on ISL1MoV neurons revealed that these neurons depolarize in response to GABA. This …

Potential biological embedding of adverse and enriching environments through epigenetic mediators
… and connectivity measures within the fronto-limbic pathway are repeatedly observed in association with ASEs. The hippocampus, amygdala, and frontal cortex, key members of the fronto-limbic pathway, support critical cognitive functions that are notably impaired in numerous mood- and …

The Influence of Age, Gender, and Thiol Repletion in an In Vivo Model of Lewy Body Disorders
… reproducible and robust α-synucleinopathy in the limbic temporal lobe following infusions of preformed α-synuclein iv fibrils into the mouse olfactory bulb, which is frequently the first brain region to display Lewy pathology in humans. Our tract-tracer studies revealed that all areas displaying …

Resting-State Functional Brain Networks in Bipolar Spectrum Disorder: A Graph Theoretical Investigation
… disrupted prefrontal control over subcortical limbic structures (Strakowski et al., 2012; Depue & Iacono, 1989). However, existing neuroimaging research on functional connectivity between frontal and limbic brain regions remains inconclusive, and is unable to adequately characterize global …

Investigations of the neurobiological and behavioural actions of cocaine
… an increase in c-Fos expression within specific limbic regions, as well as the basal ganglia. Exposure of rats to the cocaine-paired environment also produced an increase in locomotion that was associated with an increase in c-Fos expression within specific limbic regions, but not within the …
