Statistical models of effective connectivity in neural microcircuits

To appreciate how neural circuits in the brain control behaviors, we must identify how the neurons comprising the circuit are connected. Neuronal connectivity is difficult to determine experimentally, whereas neuronal activity can often be readily measured ...

Cholinergic Signals in Mouse Barrel Cortex during Active Whisker Sensing

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, Emmanuel Albert Eggermann

Internal brain states affect sensory perception, cognition, and learning. Many neocortical areas exhibit changes in the pattern and synchrony of neuronal activity during quiet versus active behaviors. Active behaviors are typically associated with desynchr ...

The In-Silico Neocortical Microcircuit

Michael Reimann

The neocortex is one of the most important brain regions, occupying more than 80% of the brain volume in mammals and contributing massively to its capability of perceiving and interpreting then environment. While it has been extensively studied, it is stil ...

Peripubertal stress-induced behavioral changes are associated with altered expression of genes involved in excitation and inhibition in the amygdala

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Orbicia Riccio Wicht

Early-life stress is a critical risk factor for developing psychopathological alterations later in life. This early adverse environment has been modeled in rats by exposure to stress during the peripubertal period-that is, corresponding to childhood and pu ...

Lateralization of the primary auditory cortex, in patients with unilateral tinnitus

Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh

Tinnitus, the chronic perception of ringing or other phantom sounds, is typically associated with hearing loss. The reduction of auditory input that conveys to auditory cortex leads to the changes in the balance of excitatory and inhibitory activation of t ...

Visual backward masking deficits in schizophrenic patients are associated with polymorphisms in the nicotinic receptor alpha 7 subunit gene (CHRNA7)

Michael Herzog, Maya Roinishvili

Visual backward masking (BM) deficits are often proposed to be trait markers for schizophrenia, revealing the genetic underpinnings of the disease. Here, we show that masking deficits in the shine-through effect are associated with polymorphisms in the nic ...

In vivo quantification of neuro-glial metabolism and glial glutamate concentration using 1H-[13C] MRS at 14.1T

Rolf Gruetter, Lijing Xin, Bernard Lanz

Astrocytes have recently become a major center of interest in neurochemistry with the discoveries on their major role in brain energy metabolism. An interesting way to probe this glial contribution is given by in vivo 13C NMR spectroscopy coupled with the ...

Longitudinal neurochemical modifications in the aging mouse brain measured in vivo by 1H magnetic resonance spectroscopy

Rolf Gruetter, João Miguel das Neves Duarte, Kim Do

Alterations to brain homeostasis during development are reflected in the neurochemical profile determined noninvasively by (1)H magnetic resonance spectroscopy. We determined longitudinal biochemical modifications in the cortex, hippocampus, and striatum o ...

Glutamatergic and GABAergic energy metabolism measured in the rat brain by 13C NMR spectroscopy at 14.1 T

Rolf Gruetter, João Miguel das Neves Duarte

Energy metabolism supports both inhibitory and excitatory neurotransmission processes. This study investigated the specific contribution of astrocytic metabolism to γ-aminobutyric acid (GABA) synthesis and inhibitory GABAergic neurotransmission that remain ...

Elucidating the role of neuron-astrocyte metabolic coupling in learning and memory

Monika Tadi

The brain has very high energy demands that are mainly met by the circulating blood glucose to ensure its proper functioning. Thus, it is not surprising that though the human brain weighs only 2- 3% of the body weight, it consumes approximately 25% of tota ...
