Differential ripple propagation along the hippocampal longitudinal axis

open access: yeseLife, 2023
Hippocampal ripples are highly synchronous neural events critical for memory consolidation and retrieval. A minority of strong ripples has been shown to be of particular importance in situations of increased memory demands.

Resistance of CA1 pyramidal cells to STZ-induced diabetes in young rats [PDF]

open access: yes, 2009
The pyramidal cell density of CA1 hippocampal subfield following STZ-induced diabetes in young rats were studied. 12 male albino 6-week Wistar rats were allocated equally in groups of normal and diabetic. Hyperglycemia induced by Streptozotocin (80 mg/kg)

Parametric Anatomical Modeling: A method for modeling the anatomical layout of neurons and their projections

open access: yesFrontiers in Neuroanatomy, 2014
Computational models of neural networks can be based on a variety of different parameters. These parameters include, for example, the 3d shape of neuron layers, the neurons' spatial projection patterns, spiking dynamics and neurotransmitter systems ...

Postnatal Development of the Primate Hippocampal Formation [PDF]

open access: yesDevelopmental Neuroscience, 2006
The hippocampal formation is a multicomponent region of the medial temporal lobe preferentially involved in declarative and relational memory processing. Behavioral studies have suggested a protracted functional maturation of these structures in primates, and postnatal developmental abnormalities in the hippocampal formation are thought to contribute ...

In search of the “I”: Neuropsychology of lateralized thinking meets Dynamic Causal Modeling

open access: yesPsychology in Russia: State of Art, 2017
Background. Ideas about relationships between “I”, egocentric spatial orientation and the sense of bodily “Self ” date back to work by classics of philosophy and psychology. Cognitive neuroscience has provided knowledge about brain areas involved in self-

Hippocampal Somatostatin Interneurons, Long-Term Synaptic Plasticity and Memory

open access: yesFrontiers in Neural Circuits, 2021
A distinctive feature of the hippocampal structure is the diversity of inhibitory interneurons. These complex inhibitory interconnections largely contribute to the tight modulation of hippocampal circuitry, as well as to the formation and coordination of

Synaptic plasticity and cognitive function are disrupted in the absence of Lrp4. [PDF]

open access: yes, 2014
Lrp4, the muscle receptor for neuronal Agrin, is expressed in the hippocampus and areas involved in cognition. The function of Lrp4 in the brain, however, is unknown, as Lrp4-/- mice fail to form neuromuscular synapses and die at birth.

Delineation of the Feline Hippocampal Formation: A Comparison of Magnetic Resonance Images With Anatomic Slices

open access: yesFrontiers in Veterinary Science, 2019
The hippocampal formation (HF) is a relevant brain structure that is involved in several neurological and psychiatric diseases. In cats, structural changes of the HF are associated with epilepsy.

A Putative Role for Ubiquitin-Proteasome Signaling in Estrogenic Memory Regulation

open access: yesFrontiers in Behavioral Neuroscience, 2022
Sex steroid hormones such as 17β-estradiol (E2) are critical neuromodulators of hippocampal synaptic plasticity and hippocampus-dependent memory in both males and females.

Loss of Immunohistochemical Reactivity in Association With Handling-Induced Dark Neurons in Mouse Brains. [PDF]

open access: yes, 2020
The handling-induced dark neuron is a histological artifact observed in brain samples handled before fixation with aldehydes. To explore associations between dark neurons and immunohistochemical alterations in mouse brains, we examined protein products ...
