The retrosplenial cortex: intrinsic connectivity and connections with the (para)hippocampal region in the rat. An interactive connectome.

open access: yesFrontiers in Neuroinformatics, 2011
A connectome is an indispensable tool for brain researchers, since it quickly provides comprehensive knowledge of the brain’s anatomical connections. Such knowledge lies at the basis of understanding network functions.

Pharmacological rescue of adult hippocampal neurogenesis in a mouse model of X-linked intellectual disability [PDF]

open access: yes, 2017
Oligophrenin-1 (OPHN1) is a Rho GTPase activating protein whose mutations cause X-linked intellectual disability (XLID). How loss of function of Ophnl affects neuronal development is only partly understood.

Transneuronal Degeneration in the Spread of Alzheimer's Disease Pathology: Immunohistochemical Evidence for the Transmission of Tau Hyperphosphorylation

open access: yesNeurobiology of Disease, 1997
Neurofibrillary tangles and dystrophic neurites appear to develop in a highly characteristic spatial and temporal sequence in AD. In order to examine the nature of the cellular progression we have studied the trisynaptic entorhinal, dentate gyrus, CA3/4 ...

Neurogenesis in the neonatal rat hippocampus is regulated by sexually dimorphic epigenetic modifiers

open access: yesBiology of Sex Differences, 2022
Highlights Neurogenesis in the dentate gyrus peaks in the early postnatal period and in the laboratory rat is significantly greater in males than females. Here we report divergent regulation of cell genesis in the neonatal dentate gyrus.

Evidence of functional mossy fiber sprouting in hippocampal formation of kainic acid-treated rats

open access: yesJournal of Neuroscience, 1985
In the rat hippocampal formation, degeneration of CA4-derived afferent fibers provokes the growth of mossy fiber collaterals into the fascia dentata. These aberrant fibers subsequently form granule cell-granule cell synapses.

Awake Reactivation of Prior Experiences Consolidates Memories and Biases Cognition. [PDF]

open access: yes, 2019
After experiences are encoded into memory, post-encoding reactivation mechanisms have been proposed to mediate long-term memory stabilization and transformation.

Consequences of Early Maternal Deprivation on Neuroinflammation and Mitochondrial Dynamics in the Central Nervous System of Male and Female Rats

open access: yesBiology
Early life stress (ELS) is associated with an increased risk for neuropsychiatric disorders, and both neuroinflammation and mitochondrial dysfunction seem to be central to mental health.

Normal and Amnesic Learning, Recognition, and Memory by a Neural Model of Cortico-Hippocampal Interactions [PDF]

open access: yes, 1993
The processes by which humans and other primates learn to recognize objects have been the subject of many models. Processes such as learning, categorization, attention, memory search, expectation, and novelty detection work together at different stages ...

Axonal regeneration in hippocampal and spinal cord organotypic slice cultures [PDF]

open access: yes, 2010
Under normal conditions, axonal regeneration after lesions is not possible in mature CNS but can occur in embryonic and early postnatal nervous systems. In recent years, a number of possible strategies to enhance axonal regeneration and eventually treat ...

Hippocampus-dependent emergence of spatial sequence coding in retrosplenial cortex. [PDF]

open access: yes, 2018
Retrosplenial cortex (RSC) is involved in visuospatial integration and spatial learning, and RSC neurons exhibit discrete, place cell-like sequential activity that resembles the population code of space in hippocampus.
