However, recent experiments have suggested that things were more complicated Although a useful technique, translating this technique to slices cultured using the interface method would be cumbersome. Supplementary material: a guillotine, an underpad, a McIlwain tissue chopper with a razor blade, filter paper, a glass Pasteur pipette with a rubber teat, 2 plastic Pasteur pipettes one of which with a wide mouth, a Petri dish, a metallic cylinder of 7 mm diameter Figure 2A. The orientation of the razor blade is indicated by the red dashed line. On its own, research on synaptic plasticity has largely benefited from two breakthrough discoveries.

    The McIlwain Tissue Chopper was designed to prepare samples of tissue for metabolic experiments and is particularly suitable for small and irregular samples. McIlwain Tissue Chopper (The Mickle Laboratory Engineering, NIH guidelines and all protocols were approved by the Institution Animal Care. the McIlwain tissue chopper for cutting fresh or fixed tissue for metabolic experiments.

    Attentively check if everything is ready instruments, temperature Brain Removal While holding still the head with the index finger and the thumb of one hand on the muzzle, make an incision with the dissecting scissors along the middle of the top of the head starting at the edge of the guillotine cut and running rostrally to the frontal bone.

    The heating system of the chamber is completed by a global heating system controlling the temperature of the entire rig.

    On one hemisphere, carefully spread the structures to see the lateral ventricle.

    Once in culture, reactive astrocytes blanket the surface of the sectioned tissue slice Cho et al. Determination of z-potential in rat organotypic hippocampal cultures. Lower the fluid level to reach the slice level, and then raise it to make it float. Each slice culture thickness was calculated from the difference in the averages of four readings from the surface of the insert membrane readings and four tissue readings.

    Associated Data Supplementary Materials Moreover, any modification of temperature or oxygenation induced an increase or a decrease of the synaptic response Figure 4.

    Once complete, two sides of the slab were again imaged and measured using Simple PCI software on a coverslip. Requirement of a critical period of transcription for induction of a late phase of LTP.

    Current methods available for measuring slice culture thickness have significant drawbacks for consecutive measurements in individual living tissues.

    In the interface environment, oxygen is supplied from the air above the tissue slice culture and nutrients are supplied from below Stoppini et al. Acute and cultured tissue slices provide easy access for experimental manipulation while maintaining morphology and electrophysiology similar to that in vivo Gahwiler et al.

    With the dissecting scissors, cut the temporalis muscle on each side, along the temporalis plate, then cut the frontal plates in the middle, transversally. Sever the fornix then gently push the hippocampus out of the cortex roll awayby inserting a spatula in the ventricle.

    1. Freshly excised tissue is sliced to a desired thickness using either a tissue chopper or a vibratome and is used for experiments immediately, or cultured and used later.

    2. External parameters are carefully controlled to obtain reproducible results. With the dissecting scissors, cut the temporalis muscle on each side, along the temporalis plate, then cut the frontal plates in the middle, transversally.

    3. Decapitation must be performed under anesthesia but cervical dislocation can also be used. A Perfusion circuit with home-made gravity perfusion system alimented by a peristaltic pump, isolated stimulation units two per electrodesurgical microscope and recording chamber.
