BDNF upregulation during declarative memory formation in monkey inferior temporal cortex

Tokuyama et al

the basics
The Basics
  • The inferior temporal cortex stores visual pair association memory.
  • Tested the hypothesis that BDNF would be upregulated in IT cortex during formation of visual pair-association memory.
  • Found BDNF was upregulated selectively in area 36 of IT cortex during PA learning, but not in areas involved in earlier stages of visual processing.
  • Suggests that BDNF contributes to reorganization of neural circuits for visual long-term memory formation in the primate
methods three experimental strategies
Methods:Three experimental strategies
  • Intra-animal comparison of mRNA expression
  • A visual memory task as the control vs. a no-task condition
  • Trained the monkeys to first learn a “rule” or “strategy” component of the tasks with training stimulus sets; a test stimulus was then introduced for new learning of declarative components.

The Basics
  • Sheep recognition: olfactory evolving to visual
  • Investigate BDNF & trk-B mRNA expression 4.5 hours post partum in olfactory/visual systems
