Nucleus accumbens dopamine and investigatory behavior : modulation by the ventral subiculum of the hippocampus through the dopamine cell bodies of the ventral tegmental area
… glutamate containing neurons from the ventral subiculum (VS) of the hippocampus. VS projections to the NAS have been suggested to influence investigatory behavior, at least in part, by evoking glutamate-mediated transmitter release from NAS dopaminergic terminals. As the VS is not known to …

Neurobiological mechanisms underlying episodic memory retrieval
… labeling, we found that dorsal subiculum had enhanced neuronal activity during memory retrieval as compared memory encoding. Taking advantage of a novel transgenic mouse line that permitted specific genetic access to dorsal subiculum neurons, we demonstrated that the hippocampal …

The Neural Substrates Supporting the Inhibition of Instrumental Avoidance Behavior
… from the entorhinal cortex through the ventral subiculum to the nucleus accumbens is the pathway that mediates the suppression of conditioned responding in response to novel contextual cues during extinction of discriminative avoidance behavior. The results supported this hypothesis, …

Hippocampal modulation of cingulate cortex and limbic thalamus during learning
… lesions of posterior cingulate cortex and subiculum in Experiment 1 as after the separate lesions in a previous study (Gabriel et al, 1987). The frequency of CR was also greater in rabbits with the combined lesions during early training. This result suggests that both cingular and subicular …

Anatomical and Functional Characterization of the Ventral Hippocampus in a Rodent Model of Schizophrenia Neuropathology
… synaptic responses in the ventral subiculum. These changes were not however, accompanied by changes in in vivo spontaneous spike activity in subicular neurons . In the mouse, MAM was found to have much less impact on brain development, as observed at the gross morphological level. …

Sex Differences in the Relationship Between Physical Activity and Cognitive Health in Ethnically Diverse Older Adults
… high PA NHW males showed larger right subiculum volumes (p≤0.01; 3-way interaction p<0.099), while high PA females had greater right CA1 and dentate gyrus volumes (p’s≤0.03; 2-way interactions p’s<0.099). PA is beneficial for cognition in older age in a sex- and ethnicity-dependent …

Cardiorespiratory fitness as a modulator of hippocampal subfield structure and function in cognitive aging
… of another hippocampal subfield, the bilateral subiculum, in older adult women, but not men. The primary goal of Experiment 2 was to examine the prediction that mnemonic discrimination-related BOLD signal in the hippocampal subfields is modulated by aging and CRF in young and older adults. In …

Hippocampal output to neocortex: Examination of the electrophysiological and plastic properties of CA1 projections to the perirhinal cortex
… circuit from the distal CA1 and proximal subiculum along with the lateral entorhinal cortex. Moreover, we investigate the roles of the hippocampus and perirhinal cortex in recognition and spatial memory. Utilising an object recognition task (a recognition memory task) and an object …

Akt signal transduction dysfunction in the 3xTg-AD mouse model of Alzheimer's disease
… amyloid plaques and NFTs, primarily in the subiculum and the CA1 layer of the hippocampal formation. Increased activity of Akt, detected with antibody to phosphoSer473-Akt, was increased in 3xTg-AD mice compared to age-matched non-transgenic mice (non-Tg), and in direct correlation to the …

Granular retrosplenial cortex layer 2/3 generates high frequency oscillation events coupled with hippocampal sharp wave-ripples and Str. LM high gamma
Encoding and consolidation of memories are two processes within the hippocampus, and connected cortical networks, that recruit different circuit level dynamics to effectively process and pass information from brain region to brain region. In the hippocampal CA1 pyramidal layer local field potential …
