Neuromodulation of neocortical microcircuitry: a multi-scale framework to model the effects of cholinergic release

Neuromodulation of neocortical microcircuits is one of the most fascinatingand mysterious aspects of brain physiology. Despite over a century of research,the neuroscientific community has yet to uncover the fundamentalbiological organizing principles under ...

Associations between genetic variations and global motion perception

Michael Herzog

The cholinergic system is known to strongly modulate perceptual and cognitive processes, and the alpha7 subunit of the cholinergic nicotinic receptor (CHRNA7) is broadly expressed within the visual system. Here, we assessed whether genetic variations of CH ...

Cellular, Synaptic and Network Effects of Acetylcholine in the Neocortex

Henry Markram, Srikanth Ramaswamy, Daniel Keller, Cristina Colangelo, Polina Shichkova

The neocortex is densely innervated by basal forebrain (BF) cholinergic neurons. Long-range axons of cholinergic neurons regulate higher-order cognitive function and dysfunction in the neocortex by releasing acetylcholine (ACh). ACh release dynamically rec ...

Visual masking in Schizophrenia: an endophenotype and its neural correlates

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Objective: In visual backward masking, a target is followed by a mask, which deteriorates performance on the target. Masking is a very sensitive endophenotype for schizophrenia. Patients and their siblings (to a lesser extent) show strong performance defic ...

Visual backward masking and the schizophrenia spectrum: EEG correlates

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Schizophrenia is a heterogeneous disease strongly influenced by genetic factors. We have previously shown that visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia (Chkonia et al., 2010). Importantly, not only patients but also ...

Rivastigmine decreases brain damage in HIV patients with mild cognitive deficits

David Paul Roger Romascano, Reto Meuli, Alessandro Daducci, Cristina Granziera, Djalel Eddine Meskaldji, Guillaume Bonnier, Ruslan Aydarkhanov, François Lazeyras

Rivastigmine has been shown to improve cognition in HIV+ patients with minor neurocognitive disorders; however, the mechanisms underlying such beneficial effect are currently unknown. To assess whether rivastigmine therapy is associated with decreased brai ...

Endophenotypes of schizophrenia: electrophysiological correlates of schizotypy

Michael Herzog, Christine Mohr, Ophélie Gladys Favrod, Guillaume Sierro

Endophenotypes are of crucial interest for schizophrenia research linking genetic abnormalities to pathology. During the last NCCR period, we have characterized one endophenotype, based on visual backward masking (VBM) deficits, behaviourally, electrophysi ...

The basal forebrain (BF) houses major ascending projections to the entire neocortex that have long been implicated in arousal, learning, and attention. The disruption of the BF has been linked with major neurological disorders, such as coma and Alzheimer's ...

Automated design of ligands to polypharmacological profiles

Daniel Constam

The clinical efficacy and safety of a drug is determined by its activity profile across many proteins in the proteome. However, designing drugs with a specific multi-target profile is both complex and difficult. Therefore methods to design drugs rationally ...

Quantitative proton spectroscopic imaging of the neurochemical profile in rat brain with microliter resolution at ultra-short echo times

Rolf Gruetter, Giulio Gambarota

Proton spectroscopy allows the simultaneous quantification of a high number of metabolite concentrations termed the neurochemical profile. The spin echo full intensity acquired localization (SPECIAL) scheme with an echo time of 2.7 ms was used at 9.4T for ...
