Derivation of a health‐based guidance value for Δ8‐tetrahydrocannabinol (Δ8‐THC) and its occurrence in food

EFSA Journal, Volume 23, Issue 11, November 2025.
Abstract The European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the derivation of a health‐based guidance value (HBGV) for Δ8‐tetrahydrocannabinol (Δ8‐THC) in food with an assessment of the occurrence of Δ8‐THC and the co‐occurrence with Δ9‐THC in hemp and hemp‐derived products.

Relationships Between Intra‐Spinal Resting‐State Functional Connectivity and Electrophysiology Following Spinal Cord Injury

Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.
Unilateral spinal cord injury in monkeys induces widespread and dynamic changes in resting‐state functional connectivity (rsFC), mirroring alterations in local field potential (LFP) coherence. Our findings reveal spatially and temporally complex intraspinal plasticity, supporting rsFC as a potential electrophysiologically grounded biomarker for ...

Geometrical shape discrimination by “Saimiri sciureus” [PDF]

Psychonomic Science, 1965
Squirrel monkeys, saimiri sciureus, which had been previously trained on visual acuity determination, were presented with six different pairs of geometric shapes. One of each pair was slightly different from the other member. Four animals in two apparatuses and tested by two different experimenters differentiated the two members of each pair 90 ...
