Viability evolutionary algorithms and applications to neuroscience and biology

Evolutionary algorithms are heuristic methods that operate on a population of individuals, which represent candidate solutions to optimization problems. Individuals with better quality, or fitness, are reproduced at a higher rate than less fit individuals ...

Connexin 30 sets synaptic strength by controlling astroglial synapse invasion

Graham Knott, Nicole Déglon

Astrocytes play active roles in brain physiology by dynamic interactions with neurons. Connexin 30, one of the two main astroglial gap-junction subunits, is thought to be involved in behavioral and basic cognitive processes. However, the underlying cellula ...

A key role for nectin-1 in the ventral hippocampus in contextual fear memory

Maria del Carmen Sandi Perez, Jocelin Grosse, Michael van der Kooij, Martina Fantin

Nectins are cell adhesion molecules that are widely expressed in the brain. Nectin expression shows a dynamic spatiotemporal regulation, playing a role in neural migratory processes during development. Nectin-1 and nectin-3 and their heterophilic trans-int ...

Lithium rescues synaptic plasticity and memory in Down syndrome mice

Diego Ghezzi

Down syndrome (DS) patients exhibit abnormalities of hippocampal-dependent explicit memory, a feature that is replicated in relevant mouse models of the disease. Adult hippocampal neurogenesis, which is impaired in DS and other neuropsychiatric diseases, p ...

Membrane potential correlates of sensory perception in mouse barrel cortex

Carl Petersen, Yves Emile Alfred Kremer, Shankar Sachidhanandam, Varun Sreenivasan, Alexandros Kyriakatos

Neocortical activity can evoke sensory percepts, but the cellular mechanisms remain poorly understood. We trained mice to detect single brief whisker stimuli and report perceived stimuli by licking to obtain a reward. Pharmacological inactivation and optog ...

The temporal dynamics of feature integration for color and form

Michael Herzog

When two visual stimuli are presented in rapid succession only one fused image is perceived. For example, a red disk followed by a green disk is perceived as a single yellow disk (e.g., Efron, Perc Psychophys, 1973). For two verniers that last 30ms each, i ...

Electrical neuroimaging of memory discrimination based on single-trial multisensory learning

Micah Murray, Antonia Thelen

Multisensory experiences influence subsequent memory performance and brain responses. Studies have thus far concentrated on semantically congruent pairings, leaving unresolved the influence of stimulus pairing and memory sub-types. Here, we paired images w ...

Lack of cyclin D2 impairing adult brain neurogenesis alters hippocampal-dependent behavioral tasks without reducing learning ability

Maria del Carmen Sandi Perez

The exact function of the adult brain neurogenesis remains elusive, although it has been suggested to play a role in learning and memory processes. In our studies, we employed cyclin D2 gene knockout (cD2 KO) mice showing impaired neurogenesis as well as d ...

A role for adult neurogenesis in dentate synaptic plasticity deficits and memory impairment in Down syndrome

Diego Ghezzi

The hippocampal dentate gyrus (DG) is one of the two sites where neurogenesis continues throughout life in the mammalian brain. Accumulating evidence suggests a unique contribution of adult-generated dentate neurons in hippocampal synaptic plasticity and h ...

Learning under stress: the inverted-U-shape function revisited

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Basira Salehi

Although the relationship between stress intensity and memory function is generally believed to follow an inverted-U-shaped curve, strikingly this phenomenon has not been demonstrated under the same experimental conditions. We investigated this phenomenon ...
