Brain Injection

Brain injections are a cornerstone technique in neuroscience research, enabling targeted delivery of viral vectors, tracers, or pharmacological agents into specific brain regions.

These (STEREOTAXIC???) injections are used for gene expression studies, optogenetic manipulation, neuronal circuit tracing, or localized drug delivery. Precision in both targeting and depth control is essential to achieve reproducible and interpretable experimental outcomes.

Typical Challenges

Manual stereotaxic brain injections are often prone to variability and technical challenges:
  • Flat skull positioning of the animal’s head required.
  • Manual drilling can lead to tissue damage. it requires trained personnel.
  • Manual depth control depends heavily on operator skill and may lead to inconsistent injection depths.
  • Even small angular misalignments or inaccuracies in skull leveling can result in off-target placements.
  • Difficulties when working in oblique trajectories due to poor angle resolution, calculation difficulties.
  • Injections performed without real-time feedback or motion correction can cause tissue damage or imprecise spread of injected material.
  • Repeatability between animals or operators is limited, complicating longitudinal or comparative studies.

Robot Steretoxic - Automated and error free brain injections

The Neurostar Robot Stereotaxic System automates the entire injection process, ensuring precision, repeatability, and tissue protection. Together, these features enable high-throughput, reproducible, and precise delivery of viral vectors or compounds — reducing user-dependent variability and improving experimental reliability.

Atlas-guided targeting

Integrated digital brain atlases and coordinate correction ensure accurate targeting even when the skull is not perfectly level.

Tilt correction

Automatically correct head alignment errors, ensuring micrometer precision without the need for perfect flat-skull leveling.

Automated depth control

The motorized injector moves with micrometer precision, allowing slow, consistent injection profiles that minimize reflux and tissue damage

Reproducible trajectories

Software-defined coordinates and motion parameters can be saved and reused for identical procedures across animals.

Smart BregmaFinder

Integrated cameras ensure consistent Bregma detection, real-time monitoring, and documentation for user-independent results.

Atlas scaling

The software adapts the atlas to size and age, ensuring consistent targeting across species and stages.

Ulttra-precise Injection control

Continuous and precisely controlled injection rates, even in the picoliter range.

Injection during movement

The needle can move slowly during injection, ensuring an optimal spread and minimal backflow.

Precise drilling calculation

Automatic computation of burr holes, even in not perfectly leveled animals

Automatic Drilling with Breakthrough detection

Simple and precise drilling through automated breakthrough recognition prevents tissue damage

Automatic synchronization

Drill and injector (needle or capillary) are fully synchronized — no manual reconfiguration or tool exchange after drilling is required.

Oblique trajectories

Access deep or lateral brain structures with the Smart Angle Device, guaranteeing smooth, repeatable trajectories and perfect alignment with specific atlas coordinates.
