A fast and inexpensive method for the behavioral determination of hearing parameters like hearing thresholds, hearing impairments or phantom perceptions (subjective tinnitus) is described. It uses pre-pulse inhibition of the acoustic startle response and can be easily implemented in a personal computer using a programmable AD/DA-converter and a piezo sensor.

Microiontophoresis entails movement of ions from a micropipette in response to a difference in electrical potential between the inside and outside of the micropipette. Biologically active molecules are thereby delivered in proportion to electrical current. We illustrate acetylcholine microiontophoresis in conjunction with micromanipulation to study endothelium-dependent vasodilation in the microcirculation.

This video demonstrates the preparation of a rat model to study retinal health and visual pathway integrity. Visual evoked potential and electroretinography reference and active electrodes are connected to the rat, followed by aligning the platform with the rat in front of the Ganzfeld bowl for even retinal illumination and closing the Faraday cage to avoid external interference.
FAQs
Calibration links the instrument’s movement to the intended position of the mounted tool, helping the operator approach the specimen accurately rather than relying on unverified alignment. It is especially important when the procedure requires controlled access to a cell, tissue, or small organism, because consistent calibration supports experimental control and can reduce specimen damage.
The key mechanical relationship is the transfer of operator movements into corresponding movements of the mounted biological tool. This lets the user position a pipette, needle, or probe with controlled access to the specimen. The accuracy of that transfer depends on calibration, stable mounting, and correct tool orientation during the setup.
Tool orientation determines how a pipette, needle, or probe reaches the specimen. Stable mounting and vibration control help preserve that access path while the system is used. Together, these conditions maintain reliable positioning, reduce the likelihood of specimen damage, and support reproducible handling during procedures that require precise manipulation.
A practical setup sequence begins by mounting the selected pipette, needle, or probe, then establishing its orientation relative to the microscope and specimen. The system is stabilized, vibration is controlled, and calibration is performed before manipulation begins. Final alignment confirms that the tool can reach the intended location with controlled movement and consistent access.
Micromanipulator setup uses a microscope together with a mounted biological tool, such as a pipette, needle, or probe. The microscope provides the viewing context for alignment, while the tool supplies the physical interface with the specimen. Stable mounting, correct orientation, calibration, and vibration control work together to maintain precise positioning.
The setup is relevant whenever a procedure requires controlled access at very small scales. Applications include cell injection, embryo manipulation, tissue dissection, and electrophysiological recording. Its value extends across cell biology, developmental biology, and biomedical research, where consistent positioning helps researchers control handling, limit specimen damage, and obtain reproducible results.
