Effects of exercise on the mechanisms of the brain

Dr. Christie is a neuroscientist studying the effects of exercise on the brain. His laboratory employs a sophisticated array of electrophysiological, immunohistochemical, molecular and behavioral research methods to elucidate learning and memory mechanisms in the aging brain.

He is particularly interested in the hippocampal formation and has conducted studies to examine its role in learning and memory throughout the lifespan. Researchers in the lab also use animal models of disorders such as Alzheimer's disease, fetal alcohol syndrome (FAS) and fragile-X syndrome to understand how neuropathologies can influence hippocampal structure and function.

Research techniques and approach

My research investigates how developmental disorders, and other pathological conditions, affect the structure and function of the hippocampal formation, a part of the brain known to be involved in learning and memory processes. I am particularly interested in how the continual introduction of new neurons into the adult brain can promote enhanced learning and memory.

My work employs several animal models of developmental disorders, including Fetal Alcohol Syndrome, Fragile-X Syndrome and Rett Syndrome. We hypothesize that these disorders affect a common set of structural and functional features in the hippocampus, and that their effects are functionally similar to those observed in Alzheimer's disease and the senescent brain.

In short, all of these disorders involve some degree of altered neurogenesis and synaptic function. I believe that carefully examining what is altered in the hippocampus by each disorder will contribute to a basic understanding of how learning and memory processes occur in the brain.

Many research programs are based around a single technical approach, and while this can have its advantages, in some cases it is somewhat self-limiting in terms of the types of research questions that can be tackled. The research questions of today and tomorrow, more often than not, will require an interdisciplinary approach to make any substantial headway.

Research techniques

In my laboratory, we use a number of sophisticated research techniques in a convergent fashion to assess hippocampal structure and function. For instance, we have recently used behavioural analysis, electrophysiology, and immunohistochemistry to show that prenatal exposure to ethanol can impact hippocampal function well into adulthood.

In addition we have also shown that exercise can largely ameliorate these hippocampal deficits. In these particular experiments we can show that reduced neurogenesis in the hippocampus recovers, that reduced synapse numbers can be restored, that reduced synaptic function can be restored, and most importantly, that behavioral functioning can be restored to normal levels.

In this particular case, we have also just recently become involved in a group of researchers that will try to determine if these same benefits can be seen in humans with FAS/E. This highlights how I like to direct my research to better understand and alleviate a particular problem in an animal model, hopefully in a manner that offers an easy transfer of knowledge to the human population.

Research approach

Clyde Hertzman, director of the Human Early Learning Partnership (HELP) is fond of using the term "from cell to society", and this really describes the outlook I try to take in my research. I believe that by focusing on how a phenomenon (i.e. neurogenesis) can impact a behavior (i.e. learning) that we will be better able to understand both normal brain function, and how a variety of pathological conditions impact the capacity of the hippocampus.

Ultimately, it is my hope to utilize the knowledge we gain about processes such as neurogenesis to help instigate the brain to actually heal itself, and thereby ameliorate the behavioural deficits that are characteristic of a wide range of disorders that involve neurodegeneration. This may sound grandiose at first, but really we have to look no further than our own skin to see how effective self regenerative mechanisms can be when they respond appropriately.

Antibody directed Immunohistochemistry and other histology techniques

Immunohistochemistry is primarily used in my laboratory to quantify where mitotic activity is occurring, and what phenotypes new cells in the brain are assuming. We can also use immunohistochemical approaches to determine the availability of different proteins at the synapse.

The biggest difference between this technique and the rest of the histological approaches we employ is that the immunohistochemistry requires confocal microscopy to precisely determine the localization of different antibodies in individual cells. We also routinely employ techniques such as Golgi analysis to determine how different manipulations change dendritic profiles, length, and synapse numbers in the hippocampus.


We really employ two distinct forms of electrophysiology in my lab, though both utilize common electrical principles.

The first area involves performing field recordings from specific structures in the brains of anaesthetized animals (in vivo).

In the second area, we use brain slice technology to perform either field or whole-cell recordings from hippocampal neurons in vitro.

Few laboratories in the world have the capacity to address functional questions using both in vitro and in vivo approaches, and I am often sought out to teach in vivo methodologies to other individuals and laboratories from around North America.

Behavioural Analysis

Because learning and memory can be quantified in the behaving animal, we often employ different behavioural tasks to determine how well animals learn different hippocampal dependent tasks (i.e. The Morris Water Maze).

Because a variety of factors can influence behavioral performance, we also routinely assay animals for anxiety and motor deficits to determine if these are impairing our capacity to quantify learning abilities in the various animal models we employ.

Human testing

Most recently we have begun to examine how learning and memory is affected in a patient population in conjunction with the BC Cancer Institute.

We have oligodendroma brain tumor patients referred to us by Dr. Brian Thiessen. We administer a series of brief mnemonic assessment tests to them before, during, and following chemotherapy.

This patient population is high functioning, and uses a chemotherapy agent that does not have severe side effects. Never-the-less, like all chemotherapy agents, it halts mitotic activity in the brain.

Our goal is to determine how this impacts learning and memory in humans -- we are carrying out this work in conjunction with animal experiments to determine exactly how much this drug affects neurogenesis and synaptic transmission in the hippocampus.

 Zoe Sharp - MSc

Research Area: The effect of exercise on neurogenesis in fmr1 KO mice; Neurogenesis(the production and survival of new neurons) is a process which is most active during development but is limited to only a few areas of the adult brain.

Multiple factors can influence neurogenesis including stress, diet, neurological disorders, and exercise. One such disorder is fragile X syndrome (FXS) which is the most common form of inherited intellectual disability and is caused by a mutation of the fmr1 gene on the X chromosome. My research concentrates on a mouse model of FXS and whether voluntary exercise modulates neurogenesis in these animals.

My project will characterize the short and long term deficits brain trauma incurs on hippocampl synaptic plasticity, in an attempt to identify a mechanism of coginitve impairments related to learning and memory observed in yourng individuals who have experienced single or multiple mild TBIs.

Christine Fontaine - MSc

Research Area: Neonate rat pups are born deaf and blind, and must therefore rely on olfaction in order to navigate in their early environment. During this early stage of life, it is possible to create a 24h memory by pairing an odor with tactile stimulation, which is evident in both behaviorally and at the synaptic level in the olfactory bulb and piriform cortex. I am extending our findings from our hippocampal work in order to assess how prenatal ethanol exposure affects learning in olfactory structures. I am complimenting my behavioral work with in vitro electrophysiology and imaging of regions of interest within the olfactory system following ethanol exposure in order to assess damage. Ongoing work aims to rescue these learning deficits using dietary supplementation and/or drug administration.

Alicia Meconi - MSc

Research Area: My research aims to investigate how oxidative stress and mitochondrial dysfunction in the hippocampus contribute to learning and memory impairment after a concussion. It will also determine whether antioxidant administration can rescue these learning and memory deficits.
