Laterality in animals: relevance to schizophrenia.

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Psychology

Background:

• Schizophrenia is associated with anomalies in neurocognitive laterality, but its role in the disorder's etiology and early development is unclear.
• Animal models have been instrumental in understanding normative neurobehavioral organization and factors influencing brain asymmetry.
• Nonhuman species are increasingly used to study factors contributing to human developmental language disorders.

Purpose of the Study:

• To propose the modification of existing animal models for studying lateralized phenomena in schizophrenia.
• To investigate the potential of animal models in understanding the genetic, environmental, and neuroendocrine factors underlying schizophrenia-related lateralization.

Main Methods:

• Review and adaptation of animal models currently used for normative neurobehavioral organization studies.
• Modification of animal models employed in the study of developmental language disorders like dyslexia.
• Application of these modified models to investigate lateralized phenomena in schizophrenia.

Main Results:

• The proposed approach offers a novel pathway to investigate the underpinnings of lateralized cognitive deficits in schizophrenia.
• Animal models can provide insights into the mechanisms and developmental trajectories of brain asymmetry relevant to schizophrenia.
• This methodology could elucidate the environmental, genetic, and neuroendocrine influences on schizophrenia.

Conclusions:

• Animal models, particularly those adapted from dyslexia research, hold significant potential for advancing our understanding of schizophrenia's lateralized aspects.
• Further research using modified animal models is warranted to explore the etiology and early development of schizophrenia-related neurocognitive anomalies.
• This interdisciplinary approach can bridge the gap between basic neuroscience and clinical psychiatry in schizophrenia research.
