title: A single mechanism can explain the speed tuning properties of MT and V1 complex neurons

authors: Perrone, John A.

subjects: speed tuning

abstract: A recent study by Priebe et al., (2006) has shown that a small proportion (27%) of primate directionally selective, complex V1 neurons are tuned for the speed of image motion. In this study, I show that the weighted intersection mechanism (WIM) model, which was previously proposed to explain speed tuning in middle temporal neurons, can also explain the tuning found in complex V1 neurons. With the addition of a contrast gain mechanism, this model is able to replicate the effects of contrast on V1 speed tuning, a phenomenon that was recently discovered by Priebe et al., (2006). The WIM model simulations also indicate that V1 neuron spatiotemporal frequency response maps may be asymmetrical in shape and hence poorly characterized by the symmetrical two-dimensional Gaussian fitting function used by Priebe et al., (2006) to classify their cells. Therefore, the actual proportion of speed tuning among directional complex V1 cells may be higher than the 27% estimate suggested by these authors.

title: On the stage Māori medium ITE: Listening to students’ voices

authors: Lee-Morgan, Jenny Bol Jun

subjects: Māori medium education

abstract: Māori-medium initial teacher education (ITE) is a small but highly important group ‘on stage’ in te ao Māori and New Zealand education. While education plays a major role in Māori language revitalisation, Māori language is also pivotal to Māori education if the aspiration ‘to live as Māori’ (Durie, 2001) is to be fulfilled. Māori-medium teachers are critical to the success of learners and their whānau who select a Māori-medium pathway and who can make a meaningful difference to the educational outcomes of Māori (Hōhepa, Hāwea, Tamatea, & Heaton, 2014). This article draws on the students’ voices in a two-year research project that centered on the development of a teaching and learning initiative within one Māori-medium ITE programme. Building on previous work by Hōhepa et al. (2014), this study adds another layer of students’ voices to understand more clearly language related issues and student experiences in Māori-medium ITE programmes. The article presents some of the complexities associated with Māori language regeneration facing students of Māori-medium ITE, with the understanding that whatever appears on the stage is always part of a greater narrative behind the scenes.
