Coronal or transverse cerebellar slices (200 μm) were cut from 18-d-old Sprague Dawley rats, as described previously (Barbour et al., 1994). Slicing and incubation solutions were adapted from Mann-Metzer and Yarom (1999) and consisted of (in mm): 85 NaCl, 2.5 KCl, 0.5 CaCl2, 4 MgCl2, 25 NaHCO3, 1.25 NaH2PO4, 75 sucrose, and 25 glucose, bubbled with 95% O2 and 5%CO2. Slices were maintained at 32°C for 1 hr, and the slicing solution was gradually replaced (1.3 ml/min) with extracellular solution containing (in mm): 125 NaCl, 2.5 KCl, 2 CaCl2, 1 MgCl2, 25 NaHCO3, 1.25 NaH2PO4, and 25 glucose. Slices were transferred to the recording chamber and, unless stated otherwise, perfused for 30 min (1.5 ml/min) with a nominally Mg2+-free extracellular solution before making recordings. All experiments were performed at 24 ± 0.5°C in the presence of 100 μm picrotoxin and 10 μm glycine, unless stated otherwise. In experiments in which 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX; Tocris Cookson, Bristol, ...
Preparation of brain slices. Postnatal day 11-14 wild-type C57BL/6 mice were decapitated, and the brains were quickly removed and immersed in oxygenated ice-cold cutting solution containing the following (in mm): 110 sucrose, 3 KCl, 7 MgCl2, 1.25 NaH2PO3, 0.5 CaCl2, 28 NaHCO3, 5 dextrose, 0.6 ascorbate, and 0.1 kynurenate. Thin (200 μm) coronal brain slices containing MS/DB were obtained using a vibroslicer (World Precision Instruments, Sarasota, FL). Slices were incubated at room temperature in artificial CSF (aCSF) for at least 60 min before being used for recording. The aCSF contained the following (in mm): 125 NaCl, 2.5 KCl, 2.0 CaCl2, 1.0 MgCl2, 1.25 NaH2PO3, 26 NaHCO3, and 10 glucose. The slices were then placed in a custom-made recording chamber, stabilized by an overlaying platinum ring strung by a plastic mesh, and perfused continuously with aCSF at a rate of 1 ml/min. All solutions used for cutting, incubating, and perfusing the slices were bubbled with 5% CO2/95% O2. Slices were ...

I basically do what you have described in your blog, with slight differences. I use a seperate bath, filled with my internal and connect it via an agarbridge (3M KCl) to my recording chamber. In the start configuration I have the internal in the pipette, the recording chamber and my ground-bath. Once the pipette makes contact with the internal in the recording chamber I use the pipette offset. BTW when entering my amp is in i=0 mode, to make sure there is no command voltage interfering. In the next step I exchange the internal in the recording chamber for my aCSF solution, dip the pipette in and read the potential. In my last step I exchange the aCSF for my internal solution to check for reversion of the potential to 0 mV, but instead the potential increases. Not to forget, I exchange the agarbridge every time I change the solution for a fresh one. As ground I use a Ag/AgCl pellet connected with the bath by an agarbridge ...

An active electrical response, the hyperpolarizing activation or H.A. response, is characteristic of L cells (a continuous line of fibroblasts) and is transmitted in a decremental manner between contiguous cells. Direct electrical coupling between pairs of L cells occurs occasionally, but transmission of the active electrical response is not dependent on such electrical connections. Some L cells are sensitive to acetylcholine but the transmitted response is not dependent on a cholinergic mechanism. 5-Iodosalicylate blocks the active electrical response. The response can be elicited readily by mechanical stimuli, and thus can serve both as a mechanical and chemical receptor mechanism and as a means of communication between cells.. ...

A plane with a point selected as an origin, some length selected as a unit of distance, and two perpendicular lines that intersect at the origin, with positive and negative direction selected on each line. Traditionally, the lines are called x (drawn from left to right, with positive direction to the right of the origin) and y (drawn from bottom to top, with positive direction upward of the origin). Coordinates of a point are determined by the distance of this point from the lines, and the signs of the coordinates are determined by whether the point is in the positive or in the negative direction from the ...

Aplysia californica (Alacrity, Redondo Beach, CA), weighing 80-120 g, were anesthetized by injection of isotonic MgCl2, and their abdominal and pleural-pedal ganglia were removed. Prior to desheathing, ganglia were treated with 0.5% glutaraldehyde for 50 s to prevent contraction of muscle cells in the remaining sheath. Ganglia were secured with minuten pins on wax in a recording chamber and desheathed in a 1:1 mixture of MgCl2 and artificial sea water. In experiments on facilitation of depressed synapses, synaptic connections between LE siphon SNs and LFS MNs in the abdominal ganglion were recorded after the left ventral surface of the ganglion was desheathed. In experiments on spike broadening in SNs, pleural ganglia were desheathed to expose the SNs in the ventrocaudal (VC) cluster.. Experiments were performed at room temperature. Ganglia were superfused with high-Mg2+/high-Ca2+ culture medium (6 × normal Ca2+, 1.6 × normal Mg2+) (Goldsmith and Abrams 1991) to reduce polysynaptic input and ...

The energetic needs of brain cells at rest and during elevated neuronal activation has been the topic of many investigations where mathematical models have played a significant role providing a context for the interpretation of experimental findings. A recently proposed mathematical model, comprising a double feedback between cellular metabolism and electrophysiology, sheds light on the interconnections between the electrophysiological details associated with changes in the frequency of neuronal firing and the corresponding metabolic activity. We propose a new extended mathematical model comprising a three-way feedback connecting metabolism, electrophysiology and hemodynamics. Upon specifying the time intervals of higher neuronal activation, the model generates a potassium based signal leading to the concomitant increase in cerebral blood flow with associated vasodilation and metabolic changes needed to sustain the increased energy demand. The predictions of the model are in good qualitative and ...

Two-photon Ca2+ imaging and electrophysiological data acquisition provide excellent tools for the study of neural cell and network activity. Using the two methods simultaneously, it is possible to follow potential fluctuations and relate them to changes in their Ca2+ levels. While the two-photon Ca2+ imaging technique shows events in multiple small areas (distinguishable parts of dendrites and spines) at high spatial resolution (less than 1 µm) but low temporal resolution (,100 ms), electrophysiology can cover changes over larger areas (cells or extensive areas) at low spatial resolution (~150 µm), and the changes can be followed considerably faster (,1 ms).. ...
