Functional Brain Imaging and Targeted Lesion Studies Using Manganese-Enhanced MRI and Focused Ultrasound in Non-Conventional ModelSpecies

The paper introduces a combined MEMRI and HIFU protocol to study brain function and lesion effects in non-conventional model species like the convict cichlid.

Problem-solving without a cortex: inferior lobe drives goal-directed object manipulation in cichlid fish

This study shows that cichlid fish use their inferior lobe, not the telencephalon, for goal-directed object manipulation in a puzzle-box task.

Different ways of evolving tool-using brains in teleosts and amniotes

This study compares brain structures of tool-using wrasses with other teleosts, finding enlarged fiber tracts in tool-users that may support higher cognitive functions, contrasting with amniotes.

Non-thalamic origin of zebrafish sensory relay nucleus: convergent evolution of visual pathways in amniotes and teleosts

The paper investigates the developmental origin of a visual relay nucleus in zebrafish, finding it arises from the midbrain rather than the forebrain, suggesting non-thalamic evolution of visual pathways.
