Sex Differences In The Anatomy Of Mam E17 Treated Rats: A Developmental Model Of Schizophrenia, Cassandra Hartsgrove Aug 2022

Sex Differences In The Anatomy Of Mam E17 Treated Rats: A Developmental Model Of Schizophrenia, Cassandra Hartsgrove

Honors Program Theses and Projects

Enlarged ventricles and reduced cortical volume are neuroanatomical abnormalities correlated with schizophrenia and typically more severe in males. The MAM model of schizophrenia is a developmental disruption model that involves exposing animals to a teratogen, methylazoxymethanol acetate (MAM), to reflect the neuroanatomical traits of schizophrenia. Rodents exposed to MAM on embryonic day 17 (E17) experience a reduction of cortical volume and increased ventricular volume. Measuring brain weight and ventricular volume can be used to inversely measure the severity of cortical reduction. The circling method was used to measure the lateral ventricles of a sample of 27 rodents; 8 MAM-females, 7 …


Decreases In The Frontal Cortical Areas Following A Developmental Disruption Model Of Schizophrenia, Anna Healy May 2021

Decreases In The Frontal Cortical Areas Following A Developmental Disruption Model Of Schizophrenia, Anna Healy

Honors Program Theses and Projects

Methylazoxmethanol Acetate (MAM) is a toxin that temporarily blocks mitosis in developing embryonic brains. Exposure in rats on embryonic day 17 (E17) selectively targets frontal and hippocampal regions of the brain and produces behavioral and anatomical effects strikingly similar to those seen in human patients with schizophrenia. While previous studies examining these induced neuroanatomical disruptions support E17 MAM exposure as an animal model of schizophrenia, the vast majority focused on male rats. However, there have been a dearth of studies specifically looking at female rats in this model. This is significant since there is evidence of sex differences in the …

Posttraumatic stress disorder (PTSD) is a trauma and stress related disorder that some people develop after exposure to a traumatic life altering event. The person must witness the traumatic event, have the traumatic event occur to a loved one, or experience a traumatic event first hand. According to the publication of the American Psychiatric Association, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnostic criteria for the identity of PTSD must include behavioral symptoms that accompany PTSD in four diagnostic clusters; re-experiencing, avoidance, negative cognitions and mood, and arousal (American Psychological Association, 2018).
