Metastable dynamics of neural circuits and networks

…, IM Park, A Fontanini, J Wang, G La Camera - Applied Physics …, 2022 - pubs.aip.org
Cortical neurons emit seemingly erratic trains of action potentials or “spikes,” and neural
network dynamics emerge from the coordinated spiking activity within neural circuits. These rich …

Neocortical pyramidal cells respond as integrate-and-fire neurons to in vivo–like input currents

A Rauch, G La Camera, HR Luscher… - Journal of …, 2003 - journals.physiology.org
In the intact brain neurons are constantly exposed to intense synaptic activity. This heavy
barrage of excitatory and inhibitory inputs was recreated in vitro by injecting a noisy current, …

Cortical computations via metastable activity

G La Camera, A Fontanini, L Mazzucato - Current opinion in neurobiology, 2019 - Elsevier
Highlights • Metastable activity is increasingly being observed in many cortical areas and in
a variety of tasks. • Metastable activity is correlated with sensory and cognitive processes …

Dynamics of multistable states during ongoing and evoked cortical activity

…, A Fontanini, G La Camera - Journal of Neuroscience, 2015 - Soc Neuroscience
Single-trial analyses of ensemble activity in alert animals demonstrate that cortical circuits
dynamics evolve through temporal sequences of metastable states. Metastability has been …

Multiple time scales of temporal response in pyramidal and fast spiking cortical neurons

G La Camera, A Rauch, D Thurbon… - Journal of …, 2006 - journals.physiology.org
Neural dynamic processes correlated over several time scales are found in vivo, in stimulus-evoked
as well as spontaneous activity, and are thought to affect the way sensory …

[HTML][HTML] Stimuli reduce the dimensionality of cortical activity

L Mazzucato, A Fontanini, G La Camera - Frontiers in systems …, 2016 - frontiersin.org
The activity of ensembles of simultaneously recorded neurons can be represented as a set
of points in the space of firing rates. Even though the dimension of this space is equal to the …

Processing of hedonic and chemosensory features of taste in medial prefrontal and insular networks

A Jezzini, L Mazzucato, G La Camera… - Journal of …, 2013 - Soc Neuroscience
Most of the research on cortical processing of taste has focused on either the primary
gustatory cortex (GC) or the orbitofrontal cortex (OFC). However, these are not the only areas …

Minimal Models of Adapted Neuronal Response to In Vivo–Like Input Currents

G La Camera, A Rauch, HR Lüscher… - Neural …, 2004 - ieeexplore.ieee.org
Rate models are often used to study the behavior of large networks of spiking neurons. Here
we propose a procedure to derive rate models that take into account the fluctuations of the …

Expectation-induced modulation of metastable activity underlies faster coding of sensory stimuli

L Mazzucato, G La Camera, A Fontanini - Nature neuroscience, 2019 - nature.com
Sensory stimuli can be recognized more rapidly when they are expected. This phenomenon
depends on expectation affecting the cortical processing of sensory information. However, …

The response of cortical neurons to in vivo-like input current: theory and experiment: I. Noisy inputs with stationary statistics

G La Camera, M Giugliano, W Senn, S Fusi - Biological cybernetics, 2008 - Springer
The study of several aspects of the collective dynamics of interacting neurons can be highly
simplified if one assumes that the statistics of the synaptic input is the same for a large …
