A subpopulation of cortical VIP-expressing interneurons with highly dynamic spines
Graham Knott, Jérôme Blanc, Christina Georgiou, Kok Sin Lee
Structural synaptic plasticity may underlie experience and learning-dependent changes in cortical circuits. In contrast to excitatory pyramidal neurons, insight into the structural plasticity of inhibitory neurons remains limited. Interneurons are divided ...
NATURE PORTFOLIO2022The functional characterization of callosal connections
Muhamed Barakovic, Giorgio Innocenti
The brain operates through the synaptic interaction of distant neurons within flexible, often heterogeneous, distributed systems. Histological studies have detailed the connections between distant neurons, but their functional characterization deserves fur ...
PERGAMON-ELSEVIER SCIENCE LTD2022SIRT7 suppresses energy expenditure and thermogenesis by regulating brown adipose tissue functions in mice
Brown adipose tissue plays a central role in the regulation of the energy balance by expending energy to produce heat. NAD(+)-dependent deacylase sirtuins have widely been recognized as positive regulators of brown adipose tissue thermogenesis. However, he ...
NATURE PORTFOLIO2022Implantable aptamer–field-effect transistor neuroprobes for in vivo neurotransmitter monitoring
While tools for monitoring in vivo electrophysiology have been extensively developed, neurochemical recording technologies remain limited. Nevertheless, chemical communication via neurotransmitters plays central roles in brain information processing. We de ...
2021Cell-type-specific nicotinic input disinhibits mouse barrel cortex during active sensing
Carl Petersen, Sylvain Crochet, Célia Roxane Gasselin, Benoît Hohl
Fast synaptic transmission relies upon the activation of ionotropic receptors by neurotransmitter release to evoke postsynaptic potentials. Glutamate and GABA play dominant roles in driving highly dynamic activity in synaptically connected neuronal circuit ...
CELL PRESS2021Distinguishing dopamine and calcium responses using XNA-nanotube sensors for improved neurochemical sensing
Ardemis Anoush Boghossian, Melania Reggente, Alice Judith Gillen, Alessandra Antonucci, Daniel Eduardo Morales Garza
To date, the engineering of single-stranded DNA-SWCNT (DNA-SWCNT) optical biosensors have largely focused on creating sensors for new applications with little focus on optimising existing sensors for in vitro and in vivo conditions. Recent studies have sho ...
2021Ageing and reinforcement learning
Michael Herzog, Wei-Hsiang Lin
Learning to achieve one’s goal in a complex environment is a complicated task. In reinforcement learning (RL) tasks, an agent interacts with the environment to learn optimal actions. In humans, striatal areas are strongly involved in these tasks. During ag ...
2021Wnt5a promotes hippocampal postsynaptic development and GluN2B-induced expression via the eIF2 alpha HRI kinase
Wnt signaling plays a key role in neurodevelopment and neuronal maturation. Specifically, Wnt5a stimulates postsynaptic assemblies, increases glutamatergic neurotransmission and, through calcium signaling, generates nitric oxide (NO). Trying to unveil the ...
NATURE RESEARCH2021Homeostatic regulation of axonal Kv1.1 channels accounts for both synaptic and intrinsic modifications in the hippocampal CA3 circuit
Homeostatic plasticity of intrinsic excitability goes hand in hand with homeostatic plasticity of synaptic transmission. However, the mechanisms linking the two forms of homeostatic regulation have not been identified so far. Using electrophysiological, im ...
NATL ACAD SCIENCES2021Combining Optogenetic Stimulation and Motor Training Improves Functional Recovery and Perilesional Cortical Activity
Silvestro Micera, Maria Pasquini, Francesco Saverio Pavone
Background. An ischemic stroke is followed by the remapping of motor representation and extensive changes in cortical excitability involving both hemispheres. Although stimulation of the ipsilesional motor cortex, especially when paired with motor training ...
