Dynamics of Hippocampal and Cortical Activation during Consolidation of a Nonspatial Memory [PDF]

open access: yes, 2006
Observations of temporally graded retrograde amnesia after hippocampal damage suggest that the hippocampal region plays a critical, time-limited role in memory consolidation.

Olig2/Plp-positive progenitor cells give rise to Bergmann glia in the cerebellum. [PDF]

open access: yes, 2013
NG2 (nerve/glial antigen2)-expressing cells represent the largest population of postnatal progenitors in the central nervous system and have been classified as oligodendroglial progenitor cells, but the fate and function of these cells remain ...

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

open access: yes, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

The cell cycle–apoptosis connection revisited in the adult brain [PDF]

open access: yes, 2005
Adult neurogenesis is studied in vivo using thymidine analogues such as bromodeoxyuridine (BrdU) to label DNA synthesis during the S phase of the cell cycle.

Functional Integration of Neuronal Precursors in the Adult Murine Piriform Cortex

open access: yesCerebral Cortex, 2019
The extent of functional maturation and integration of nonproliferative neuronal precursors, becoming neurons in the adult murine piriform cortex, is largely unexplored.

Spike frequency adaptation affects the synchronization properties of networks of cortical oscillators [PDF]

open access: yes, 1997
Oscillations in many regions of the cortex have common temporal characteristics with dominant frequencies centered around the 40 Hz (gamma) frequency range and the 5–10 Hz (theta) frequency range.

Altered functional connectivity within the default mode network in two animal models with opposing episodic memories. [PDF]

open access: yesPLoS ONE, 2018
Memory enhancement and memory decline are two opposing cognitive performances commonly observed in clinical practice, yet the neural mechanisms underlying these two different phenomena remain poorly understood. Accumulating evidence has demonstrated that

Smell-induced gamma oscillations in human olfactory cortex are required for accurate perception of odor identity.

open access: yesPLoS Biology, 2022
Studies of neuronal oscillations have contributed substantial insight into the mechanisms of visual, auditory, and somatosensory perception. However, progress in such research in the human olfactory system has lagged behind.

Cellular Plasticity in the Adult Murine Piriform Cortex: Continuous Maturation of Dormant Precursors Into Excitatory Neurons

open access: yesCerebral Cortex, 2018
Neurogenesis in the healthy adult murine brain is based on proliferation and integration of stem/progenitor cells and is thought to be restricted to 2 neurogenic niches: the subventricular zone and the dentate gyrus.
