- Long term follow-up after multiple hippocampal transection (MHT).
- Patil AA, Andrews R.Author information University of Nebraska Medical Center, Division of Neurosurgery, 982035 Nebraska Medical Center, Omaha, NE 68198-2035, USA. Electronic address: apatil@unmc.edu.AbstractPURPOSE: Multiple hippocampal transection (MHT) is a new surgical procedure which disrupts seizure propagation within the hippocampus without impairing verbal memory or the loss of stem cells. Since there are very few papers on this procedure, the authors are presenting their long term results to increase the database on this procedure.

- Neonatal amygdala lesions alter basal cortisol levels in infant rhesus monkeys.

The current study examined the effects of neonatal amygdala lesions on basal HPA function and the postnatal testosterone (T) surge of rhesus monkeys reared with their mothers in large outdoor social groups. An early morning basal blood sample was collected at 2.5 months of age, whereas at 5 months samples were collected not only at sunrise, but also at mid-day and sunset to examine the diurnal rhythm of cortisol. At 2.5 months of age sham-operated males exhibited higher cortisol than females, but this sex difference was abolished by neonatal amygdalectomy, with lesioned males also showing lower basal cortisol than controls. Although neonatal amygdalectomy did not alter the postnatal T surge, there was a positive relationship between T and basal cortisol levels. At 5 months of age, neither the sex difference in cortisol, nor its correlation with T levels were apparent any longer. Instead, the diurnal cortisol rhythm of both males and females with amygdalectomy showed a blunted decline from mid-day to sunset compared to controls. These results indicate that neonatal amygdala damage alters basal HPA function in infant rhesus monkeys, affecting males only at early ages (at 2.5 months), while leaving the postnatal T surge intact, and resulting in a flattened diurnal rhythm in both genders at the later ages. Thus, the primate amygdala has a critical influence on the HPA axis in the first few months of life.

- Sex-dependent role of the amygdala in the development of emotional and neuroendocrine reactivity to threatening stimuli in infant and juvenile rhesus monkeys.
- Raper J, Wallen K, Sanchez MM, Stephens SB, Henry A, Villareal T, Bachevalier J.Author information Department of Psychology, Emory University, 36 Eagle Row, Atlanta, GA 30322, USA. jraper@emory.eduAbstractAmygdala dysfunction and abnormal fear and stress reactivity are common features of several developmental neuropsychiatric disorders. Yet, little is known about the exact role the amygdala plays in the development of threat detection and emotional modulation. The current study examined the effects of neonatal amygdala lesions on defensive, emotional, and neuroendocrine reactivity of infant rhesus monkeys reared with their mothers in large species-typical social groups. Monkeys received either bilateral MRI-guided ibotenic acid amygdala (Neo-A; n = 16) or sham (Neo-C; n = 12) lesions at 24.8 ± 1.2 days of age, or served as behavioral control (Neo-BC; n = 3). Defensive and emotional responses were assessed using the Human Intruder paradigm as infants and as juveniles (2.5 and 12 months of age, respectively), whereas neuroendocrine reactivity was only examined during the juvenile period. As infants, Neo-A animals expressed similar levels of freezing and hostile behaviors as compared to controls, whereas during the juvenile period Neo-A animals expressed significantly less freezing compared to controls. Interestingly, the sex of the infant modulated the behavioral effects of neonatal amygdalectomy, leading to different patterns of behavior depending on the sex and lesion status of the infant. Unlike controls, Neo-A infants did not modulate their behavioral responses based on the salience of the threat. The impact of neonatal amygdalectomy increased with age, such that Neo-A juveniles exhibited fewer emotional behaviors and increased cortisol response to the stressor as compared to controls. These data indicate that the amygdala plays a critical role in the development of both emotional and neuroendocrine reactivity as well as the expression of sexually dimorphic emotional expression.
