Dopamine and sleep have been independently linked with hippocampus-dependent learning."
BDNF is required for reconsolidation of fear extinction memory. "
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"
May 27, 2015
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"
May 13, 2015
Cortical GABAergic interneurons constitute an extremely diverse population of cells organized in a well-defined topology of precisely interconnected cells."
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."
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."
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."
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"
Jun 16, 2015
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."
The Changing Brain Symposium is a Satellite event to IBRO 2015. Organized by Dr. Marcos R. Costa (Brain Institute, Natal) and Dr. Cecilia Hedin Pereira (Oswaldo Cruz Foundation, Rio de Janeiro), the symposium will discuss new advances in the study of brain development and adult neurogenesis."
