Can vocal conditioning trigger a semiotic ratchet in marmosets?

The complexity of human communication has often been taken as evidence that our language reflects a true evolutionary leap, bearing little resemblance to any other animal communication system.

Automated analysis of free speech predicts psychosis onset in high-risk youths

Psychiatry lacks the objective clinical tests routinely used in ther specializations. Novel computerized methods to characterize complex behaviors such as speech could be used to identify and predict sychiatric illness in individuals.

Emergence of invariant representation of vocalizations in the auditory cortex

An essential task of the auditory system is to discriminate between different communication 33 signals, such as vocalizations. In everyday acoustic environments, the auditory system needs 34 to be capable of performing the discrimination under different acoustic distortions of 35 vocalizations.

Multifactoriality in Psychiatric Disorders: A Computational Study of Schizophrenia

This computational work shows that schizophrenia phenotypes can be produced by a myriad of causes at the molecular and circuit levels, which suggests that unified explanations for either the full syndrome or its behavioral and network endophenotypes are unlikely to be expected at the genetic and molecular levels.

Parturition Signaling by Visual Cues in Female Marmosets (Callithrix jacchus)

Skin reflectance spectra at different stages of pregnancy. Reflectance spectra from the genitalia and the thighs of one subject (Female C) measured throughout two weeks following (+1 to +2) and four weeks preceding (-4 to -1) parturition.

The Psychedelic State Induced by Ayahuasca Modulates the Activity and Connectivity of the Default Mode Network

The experiences induced by psychedelics share a wide variety of subjective features, related to the complex changes in perception and cognition induced by this class of drugs.

Synaptic Homeostasis and Restructuring across the Sleep-Wake Cycle

Sleep is critical for hippocampus-dependent memory consolidation. However, the underlying mechanisms of synaptic plasticity are poorly understood. The central controversy is on whether long-term potentiation (LTP) takes a role during sleep and which would be its specific effect on memory.

Input and Output Gain Modulation by the Lateral Interhemispheric Network in Early Visual Cortex

Neurons in the cerebral cortex are constantly integrating different types of inputs. Dependent on their origin, these inputs can be modulatory in many ways and, for example, change the neuron's responsiveness, sensitivity, or selectivity.

Interplay of environmental signals and progenitor diversity on fate specification of cortical GABAergic neurons

Cortical GABAergic interneurons constitute an extremely diverse population of cells organized in a well-defined topology of precisely interconnected cells.

Specification of excitatory neurons in the developing cerebral cortex: progenitor diversity and environmental influences

The mature cerebral cortex harbors a heterogeneous population of glutamatergic neurons, organized into a highly intricate histological architecture. Classically, this mixed population of neurons was thought to be generated sequentially from a seemingly homogenous group of progenitors under the influence of external cues.
