| It is understandable that those brains which all authors agree to call macrosmatic have low cerebra, with the bulbi in an anterior position. |
|
| As is generally known, one can distinguish between macrosmatic and microsmatic species of fishes. |
|
| The situation in macrosmatic laboratory animals, such as rats, rabbits and guinea pigs seems, at least at first sight, to be considerably less controversial. |
|
| Although a vague bulge appears behind the anterior olfactory nucleus, it is highly questionable if this should be considered to be homologous with the olfactory tubercle in macrosmatic mammals. |
|
| However, while synthesis may play a crucial role in object recognition, segregating odors of interest from complex backgrounds is crucial for the survival of many macrosmatic species. |
|
| In comparison with the OR gene repertoires in rodents and dogs which are macrosmatic animals, primates are thought to have relatively fewer number of intact OR genes and higher fraction of pseudogenes. |
