WebJul 20, 2024 · Previous techniques to increase the viability of brain slices focused on reducing cytotoxicity by chemical means, including alterations of the artificial cerebrospinal fluid (aCSF) composition to alleviate the direct damage of the slicing procedure or adding protective antioxidants to reduce cellular deterioration. Artificial cerebrospinal fluid (aCSF) is a buffer solution prepared with a composition representative of cerebrospinal fluid that is used experimentally to immerse isolated brains, brain slices, or exposed brain regions to supply oxygen, maintain osmolarity, and to buffer pH at biological levels. ACSF is commonly used for electrophysiology experiments to maintain the neurons that are being studied.
WebQuestion: The composition of the aCSF solution was (in mM): NaCl (145), KCl (2.5), CaCl2 (2), MgCl2(2), 10 HEPES (10, pH 7.4), glucose (10). The aCSF also contained drugs to block ionotropic GABA receptors (picrotoxin) and sodium channels (tetrodotoxin a.k.a. TTX) Why do we still observe excitatory synaptic currents in the presence of TTX? WebNov 26, 2024 · For physiological relevance, the aCSF composition mimicked the mammalian ionic CSF composition and consisted of (in mM): NaCl 124, NaHCO 3 26, KCl 3.2, MgSO 4 1, NaH 2 PO 4 0.5, CaCl 2 1.1, and glucose 10, and bubbled with 95% O 2 and 5% CO 2 (pH 7.4) ( Gleizes et al., 2024 ).
