Cocaine Sensitization in BDNF Knockout Mice
Objective: To examine locomotor sensitization to repeated cocaine doses in heterozygous BDNF knock-out mice compared with wild-type littermates
This is a Cocaine Sensitization in BDNF Knockout Mice protocol using mouse as the model organism. The procedure involves 4 procedural steps, 2 materials. Extracted from a 1999 paper published in Journal of Neuroscience.
Model and subjects
mouse • BDNF heterozygous knock-out and wild-type littermates • unknown • Not specified • Not specified
Study window
Estimated timing pending
Core workflow
Baseline assessment • Repeated cocaine administration • Measure locomotor activity
Primary readouts
- Locomotor activity in response to cocaine
- Development of sensitization to repeated cocaine doses
- Comparison of sensitization rate between BDNF knock-out and wild-type mice
Key equipment and reagents
Use this page as an execution guide, then fall back to the source paper whenever you need exact exclusions, dosing details, or assay-specific caveats.
Confirm first
- Verify the animal model, intervention setup, and collection timepoints against the source paper.
- Check that every direct vendor link matches the exact specification your lab plans to run.

Baseline assessment
Establish baseline locomotor activity in heterozygous BDNF knock-out mice and wild-type littermate controls prior to cocaine administration
Note: This is the control condition for comparison
View evidence from paper
“we examined locomotor sensitization to cocaine in heterozygous BDNF knock-out mice and found that the development of sensitization was delayed compared with wild-type littermates”
Repeated cocaine administration
Administer cocaine doses to both heterozygous BDNF knock-out mice and wild-type littermates via intraperitoneal injection at doses of 5-15 mg/kg
Note: Doses range from 5-15 mg/kg administered intraperitoneally
View evidence from paper
“the psychomotor stimulant effects of cocaine (5–15 mg/kg, i.p.) were studied”
Measure locomotor activity
Monitor and record locomotor activity in response to repeated cocaine doses in both genotypes

Compare sensitization development
Compare the development of locomotor sensitization between heterozygous BDNF knock-out mice and wild-type littermates across repeated cocaine administrations
Note: Primary outcome comparison between genotypes
