Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Accumulating neurobiological evidence demonstrates that certain neurons can undergo neurotransmitter phenotype switching, transitioning from an excitatory to an inhibitory profile during development or in response to injury.

The analysis

The claim is specific and empirical. Multiple papers directly support the phenomenon of neurons switching their neurotransmitter phenotype (e.g., from excitatory to inhibitory or glutamatergic to GABAergic) during development or after spinal cord injury. No papers refute the claim.

Bertels et al. (2022) demonstrate that adult spinal cord injury prompts neurotransmitter phenotype switching of spatially defined excitatory interneurons to an inhibitory phenotype.
