A very new study shows that fatty acid enriched formulas DO NOT make 
brains develop the same way human milk does. See the new study below. 
I've NOT read the entire thing yet, a friend is getting a copy for me, I 
don't have access to this journal (Developmental Neuropsychology).

Numerous studies report positive effects of breast-feeding on infant 
development. Such effects are apparent early in development as well as 
in later years. Recently, elements in breast milk, polyunsaturatred 
fatty acids (PUFAs), have been identified as having great potential for 
increasing nutritional benefits. PUFAs are long-chain fatty acids 
containing two or more double bonds. While some scientists are 
enthusiastic about the long-term benefits of PUFAs on brain and 
cognitive development, many of the positive pharmacological effects 
attributed to PUFAs remain unsubstantiated. The present study 
investigated the differential impact of breast-feeding vs. PUFA-enriched 
formula in a small but well-matched population of 12 infants tested at 6 
months of age. Event-related potential (ERP) and a range of behavior 
measures were recorded. ERP waveforms identified marked differences 
between the breast-fed and PUFA-fed infants by 6 months of age. When a 
range of biological, perinatal, and cognitive factors were equated 
between the two groups, only the ERPs recorded from breast-fed infants 
changed throughout their recorded period (700 msec), differentiated 
between all speech sounds, and generated differences in scalp recordings 
across all regions recorded across both hemispheres. Such differences in 
the range of their brain responses could signal an advantage for the 
breast-fed infants for later linguistic and cognitive development.
