Motion contrast in primary visual cortex: a direct comparison of single neuron and population encoding

We analyzed firing rates and phase-locking to low-gamma frequency in single cells and neuronal assemblies. Motion contrast was reflected in all measures but in semi-independent populations.

Extracting information from the shape and spatial distribution of evoked potentials.

Over 90 years after its first recording, scalp electroencephalography (EEG) remains one ofthe most widely used techniques in human neuroscience research, in particular for the study of event-related potentials (ERPs).

Subtle Alterations in Spatial Memory Induced by Amyloid Peptides Infusion in Rats

In the present study, we evaluated the effects of a low-dose 15-day long treatment with Ab peptides on spatial and non-spatial strategies of rats tested in the Barnes maze. Ab peptides (0.5 mL/site/day; 30 pmoL solution of Ab1–40:Ab1–42 10:1) or saline were bilaterally infused into the CA1 (on the first treatment day) and intraventricularly (on the following 15 days) in 6-month-old Wistar male rats.

Live Imaging Followed by Single Cell Tracking to Monitor Cell Biology and the Lineage Progression of Multiple Neural Populations

Understanding the mechanisms that control critical biological events of neural cell populations, such as proliferation, differentiation, or cell fate decisions, will be crucial to design therapeutic strategies for many diseases affecting the nervous system.

Specifc Phospholipids Regulate the Acquisition of Neuronal and Astroglial Identities in Post-Mitotic Cells

Embryonic stem cell diferentiation in specifc cell lineages is a major issue in cell biology, and particularly, in regenerative medicine. Neural stem cells (NSCs) have the potential for self-renewal and diferentiation into neurons, astrocytes and oligodendrocytes.

The interpretation of dream meaning: Resolving ambiguity using Latent Semantic Analysis in a small corpus of text

Computer-based dreams content analysis relies on word frequencies within predefined categories in order to identify different elements in text.

The language of geometry: Fast comprehension of geometrical primitives and rules in human adults and preschoolers

Here, we ask whether a “geometrical language” with recursive embedding also underlies the human ability to encode sequences of spatial locations.

4.10 – Multiple Stages of Memory Formation and Persistence

The idea that memories are not made instantly after learning but need to undergo a time-dependent, metabolically active complex consolidation process before they can be stably stored has dominated the neuroscience of learning and memory for decades.

Short term changes in the proteome of human cerebral organoids induced by 5-MeO-DMT

Here we used shotgun mass spectrometry to explore proteomic differences induced by 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) on human cerebral organoids. Out of the 6,728 identified proteins, 934 were found differentially expressed in 5-MeO-DMT-treated cerebral organoids.

Sleep, Synaptic Plasticity, and Memory

The mechanisms underlying the intimate connection between sleep and learning are becoming increasingly clear.

Asymmetry of the temporal code for space by hippocampal place cells

Here we show that the spike timing of place cells couples to theta phase before major increases in firing rate, anticipating the animal’s entrance into the classical, rate-based place field.

Place and grid cells in a loop: implications for memory function and spatial coding

Based on the anatomy of the entorhinal-hippocampal circuitry, we constructed a model of place and grid cells organized in a loop to investigate their mutual influence in the establishment of their codes for space.
