CLINICAL IMPLICATIONS
& Memory impairments in schizophrenia cannot be attributed to alterations in size
ofhippocampal neurons.
& Reduction in size of the hippocampus in schizophrenia is not explained by reduced
hippocampal neuron size.
LIMITATIONS
& The sample sizes are relatively small.
& There is the possibility of a type II error (failure to detect a true difference
between the brains of people with and without schizophrenia).
& The hippocampus was analysed as a whole, so changes in a part, such as the
anterior half, might have been missed.
