Histology
Expert in several histological techniques and tissue processing, including, but not limited to, cell body stains, Gold Chloride fiber stains, Bodian staining, AChE histochemistry, ChAT histochemistry, NADPH-d histochemistry, and several Golgi impregnation techniques.
Highly proficient in frozen (including rapid freezing) and paraffin embedded tissue mounting and slicing techniques using microtome and cryostat.
Highly proficient in chemical fixation and preservation of neural tissue.
Expert in anatomical and morphological analysis of neural tissue using light and fluorescent microscopy.
Highly skilled in detailed graphic reconstruction of neuronal cells and morphology using digital imaging and camera lucida.
Neuronal Tract Tracing
Highly experienced in central injections of both retrograde and anterograde neuronal tracers, using stereotaxic coordinates.
Highly experienced in peripheral injections of anterograde neuronal tracers.
Highly experienced in intraocular injections of anterograde neuronal tracers.
Knowledge of neuronal tract tracers include, but are not limited to, HRP, WGA-HRP, Flourogold, Texas Red, Biocytin, Evans Blue, and DiI.
Neurosurgery
Successfully completed ACC training in GC470, “Essentials for Animal Care and Research”.
Proficient in the regulations, humane principles, and ethical considerations involving the appropriate use of animals for research and teaching purposes.
Highly experienced in stereotaxic neurosurgery.
Proficient in anesthetics, postoperative procedures, and euthanasia.
Proficient in aseptic techniques.
Behavioral Studies
Designed and constructed radial arm maze paradigm to test spatial organization and spatial navigation of rodent subjects.
Designed behavioral experiments to investigate physiological and anatomical substrates of sensory motor integration in adult, juvenile and neonatal subjects. Paradigms consisted of presenting various stimuli to the skin, facial vibrissae, and body vibrissae in different patterns and time sequences to physiologically and behaviorally characterize responses, in order to understand how animals integrate sensory information in the guidance of behavior.
Electrophysiology
Working knowledge of intracellular and extracellular recording techniques in vertebrate and invertebrate systems.
Working knowledge of oocyte expression systems recording techniques.
Human subjects
Experienced in obtaining physiological and behavioral measurements from human subjects.
