Accurate resistivity mouse brain mapping using microelectrode arrays

Philippe Renaud, Vincent Delattre, Patrick Fraering, Amélie Barbara Hildegarde Béduer, Sébastien Mosser, Pierre Joris

Electrical impedance spectroscopy measurements were performed in post-mortem mice brains using a flexible probe with an embedded micrometric electrode array. Combined with a peak resistance frequency method this allowed obtaining intrinsic resistivity valu ...

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 ...

VGLUT1 is localized in astrocytic processes in several brain regions

Mats Julius Stensrud

During the last years, the concept of gliotransmission has been established. Glutamate has been shown to be released from astrocytes by different mechanisms, e.g., in an exocytotic manner. The authors have previously shown that astrocytes in the dentate-mo ...

From its introduction, in utero electroporation has arisen as a powerful tool to manipulate neural-precursor cells of the parietal cortex and their progeny in vivo. Although this technique has unlimited potentials for targeting numerous brain areas, the ex ...

High-Performance And Site-Directed In Utero Electroporation By A Triple-Electrode Probe

Diego Ghezzi

From its introduction, in utero electroporation has been recognized as a powerful tool to manipulate neural-precursor cells of the parietal cortex and their progeny in vivo. Although this technique has unlimited potentials for targeting numerous brain area ...

Automated quality control in MR-based brain morphometry

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Bénédicte Marie Maréchal, Delphine Ribes Lemay, Reto Meuli, Alexis Roche

Normal aging and a wide range of neurologic, inflammatory or psychiatric diseases lead to changes in the brain tissue over time. In the interest of diagnosis, prognosis and treatment monitoring, it is highly desirable to have robust tools that reliably mea ...

Separate encoding of model-based and model-free valuations in the human brain

Behavioral studies have long shown that humans solve problems in two ways, one intuitive and fast (System 1, model-free), and the other reflective and slow (System 2, model-based). The neurobiological basis of dual process problem solving remains unknown d ...
