• Le cortex cingulaire, représenté dans des nuances de violet ci-dessous, est connu pour exprimer une grande quantité de récepteurs 5HT-2Ar. Les préférés de la psilocybine. Il est divisé en plusieurs zones, dont le cortex cingulaire antérieur rostro-ventral (CCA rostral, en violet très foncé). Ce serait ce CCA rostral qui induirait des réponses différentes à la psilocybine.

• A myotome is considered as intact, if it is graded 3 or 4 and the next rostral myotome is graded as intact including the implication on the ML determination.

• A potential possible mechanism of sympathoinhibition caused by SGLT2 and/or SGLT1 inhibitors in the improvement of cardiorenal outcomes. SGLT2 and SGLT1 inhibitors could block SGLT2 and SGLT1, which are colocalized in the bulbospinal rostral ventrolateral medulla (RVLM) neuron and thus hyperpolarized membrane potential, and then transmit reduced sympathetic nerve activity (SNA) through intermediolateral cell column (IML) to the peripheral tissues including heart, kidneys, and arterioles, eventually improving cardiorenal outcomes

• The intrathecal (IT) dosing route introduces drugs directly into the CSF to bypass the blood–brain barrier and gain direct access to the CNS. We evaluated the use of convective forces acting on the cerebrospinal fluid as a means for increasing rostral delivery of IT dosed radioactive tracer molecules and antisense oligonucleotides (ASO) in the monkey CNS. We also measured the cerebral spinal fluid (CSF) volume in a group of cynomolgus monkeys.

• According to vertebrate paleontologist Todd Cook, associate professor of biology, Penn State Behrend, the team did not set out to contribute to the debate about the origins of teeth. Instead, he and his colleagues were studying the tissue structure of rostral denticles, which are the jagged spikes that run along the elongated snouts of sawsharks and sawfishes and are used in foraging and self-defense. Cook, who is the lead author of the study, which appears in the Journal of Anatomy, noted that sawfishes belong to the same group as skates and rays and are closely related to sharks.

• Investigating the association between neurodegeneration within rostral spinal cord and brain gray matter volume (GMV) and assessing the relationship between remote neurodegenerative changes and clinical outcomes at the early phase of Cervical Spondylotic Myelopathy (CSM).

• A previous study showed that ESC-derived NE created by using this culture method goes on to express a rostral forebrain marker, Rax (also called Rx)24. Because of this, we used Rax::GFP ESC to monitor the formation of the rostral forebrain. Live imaging analysis showed that small patches of Rax::GFP+ cells first appeared in a speckled pattern (Fig. 1a and Supplementary Movie 1). By day 5, the Rax::GFP+ signals became noticeably stronger in one half of the aggregate (Fig. 1a), and this rostral-polarization trend continued through the next two days (Fig. 1a; see ratio of rostral-polarized pattern in Supplementary Fig. 1D).
